It supports Linux and all popular open-source middleware including Apache, MySQL, JBoss and Ruby on Rails, so there is no learning curve to slow down your team.<br /> <a href="applogic-faqs#top">Back to Top</a></p> <p><a name="function"></a><strong>Will these grid servers function like my dedicated server?</strong><br /> Yes – you get full root access to the appliance on the grid. This includes root and WHM access just like any other dedicated server.<br /> <a href="applogic-faqs#top">Back to Top</a></p> <p><a name="different"></a><strong>How is a grid server different from a regular server?</strong><br /> A grid server behaves just like a regular dedicated server. It runs its own copy of Linux, and you get root access. The only differences are built-in high availability, the ability to take whole-site snapshots, and on-demand scalability.<br /> <a href="applogic-faqs#top">Back to Top</a></p> <p><a name="sites"></a><strong>What kinds of sites can I host on your grid?</strong><br /> AppLogic is designed to support web applications, including streaming media, VoIP, heavy database input/output, and high volumes of ecommerce transactions. It is completely compatible with Linux operating systems, as well as popular open source middleware such as Apache, MySQL, JBoss and Ruby on Rails.<br /> <a href="applogic-faqs#top">Back to Top</a></p> <p><a name="multiple"></a><strong>Can I host multiple websites on the same grid server?</strong><br /> Absolutely! We even offer grid servers with cPanel, so that you can easily create and manage multiple domains.<br /> <a href="applogic-faqs#top">Back to Top</a></p> <p><a name="bandwidthram"></a><strong>Can additional bandwidth, storage and RAM be added?</strong><br /> Bandwidth, RAM and CPU can be changed on the fly. Changing of the volume size will require a short downtime for the copy & resize process to complete. The amount of down time is determined by the amount of data you have to copy and the size of the previous copy. A bit by bit copy is done during this process which is roughly 2mins per 1 GB of data.<br /> <a href="applogic-faqs#top">Back to Top</a></p> <p><a name="space"></a><strong>What happens when you run out of space on your grid?</strong><br /> We’ll add more servers! It really is as simple as it sounds. With 3Tera’s AppLogic grid OS, we can add, remove and replace servers seamlessly without disrupting any customer websites.<br /> <a href="applogic-faqs#top">Back to Top</a></p> <p><a name="backup"></a><strong>What about backups and security?</strong><br /> There is a backup and snapshot feature which allows us to make a copy of your install file system. Depending on the file system and type of data we may require a short amount of downtime to make the copy. Once the copy is made it can be transferred like any other disk image. As for security all grid nodes are locked down to maintainer access only with firewalls and other security features put in place. We also have a front end DDoS mitigation service that will be available for clients hosted on the grid to use. Each appliance on the grid is setup as a virtual dedicated server with only access given to you and our staff if needed via local console.<br /> <a href="applogic-faqs#top">Back to Top</a></p> <p><a name="crash"></a><strong>What happens if a grid server crashes? Does the whole grid fail?</strong><br /> Our grid is comprised of many nodes. If any of the stand alone nodes were to fail your application and mirrored data would be automatically redeployed on the next available appliance. This typically takes roughly 5 minutes and has no human intervention. If the controller of the node were to go down then the entire grid will reboot and resync itself. This process takes 10-15 minutes depending on the amount of hosts went down but will eventually fully restore itself with no human intervention needed.<br /> <a href="applogic-faqs#top">Back to Top</a></p> <p><a name="bind"></a><strong>Can I bind multiple IPs to the same grid server?</strong><br /> Of course! In fact, each domain on a grid server can have its own IP address and SSL certificate.<br /> <a href="applogic-faqs#top">Back to Top</a></p> <p><a name="systems"></a><strong>What kind of systems would I need to purchase from you now to support all my clients?</strong><br /> You can start off with the smallest 20GB and scale out from there to get a larger Disk and CPU allowance or go with our utility based model and pay as you go. You can also purchase a private grid array which allows you to have much more control of the environment. We offer these at racks of 4 nodes or more.<br /> <a href="applogic-faqs#top">Back to Top</a></p> <p><a name="nodes"></a><strong>How many nodes can I scale to?</strong><br /> 256<br /> <a href="applogic-faqs#top">Back to Top</a></p> <p><a name="cost"></a><strong>How much will this cost me?</strong><br /> Wrong question.

When you run an application on the AppLogic grid, it manufactures all infrastructure pieces needed for it on demand, assembles and configures them and runs your code on top. When you stop the application, AppLogic tears down the infrastructure.</p> <p><img src="http://www.domaingurus.com/images/1.jpg" alt="AppLogic Grid Computing" /></p> <p>This makes an enormous difference on what you can do with your application. To start with, you no longer need to own special hardware: the application is completely self-contained and will run on any grid of commodity servers. Without the tie-in to hardware, all you need to assemble and manage applications is a browser, so you can do it from anywhere in the world.</p> <p>Plus, when you need additional performance, it takes just minutes to increase the resources allocated to your application. You can add more servers as needed, forget about over-provisioning.<br /> <a href="topic/how-about-applogic#top">Top of Page</a></p> <h3>How do I manage all this?<a name="manage"></a></h3> <p><img src="http://www.domaingurus.com/images/2.jpg" alt="AppLogic Cloud Computing" /></p> <p>With AppLogic, all servers, storage, applications and users are managed from a single, browser-based management console. AppLogic also comes with a scriptable command-line interface that makes it easy to provision applications and scale them on the fly with a script.<br /> <a href="topic/how-about-applogic#top">Top of Page</a></p> <h3>How does AppLogic Work?<a name="work"></a></h3> <p>AppLogic replaces infrastructure hardware such as firewalls, load balancers, network attached storage (NAS), storage area networks (SAN) and others with disposable infrastructure components that are implemented entirely in software and run on the grid as an integral part of each application. The technology that enables this is called disposable infrastructure. It allows to package existing operating systems and middleware into disposable components that are easy to configure, assemble and include with your application. Rather than installing software on servers, applications on AppLogic are assembled from virtual appliances. Each appliance is a completely virtualized runtime environment and software stack.</p> <p><img src="http://www.domaingurus.com/images/3.jpg" alt="AppLogic Software Stack" /></p> <p>For example, with AppLogic you can build a database appliance by combining your favorite Linux distro and database engine. The resulting appliance is easy to instantiate, configure and assemble with other such appliances wherever a database is needed. This way, N-tier applications become hardware-independent, which makes them easy to deploy and scale.</p> <p>Instead of assembling hardware and then spending weeks cobbling together all the software to make it work, with AppLogic you simply open a browser and use the friendly graphical user interface to take a firewall, load balancer, web server and any other component, drag them on screen and connect. Then you add the HTML files, code, database and content specific for your application. Now with a single hit of a button you can produce a portable executable image of your entire application that includes all of the above and runs on any grid.<br /> <a href="topic/how-about-applogic#top">Top of Page</a></p> <h3>Is AppLogic for me?<a name="forme"></a></h3> <ul> <li>If you are a Web 2.0 company, AppLogic enables you to scale to hundreds of thousands of users without spending effort and money on IT infrastructure. With AppLogic, you can scale your application incrementally from a single server to hundreds of servers without owning hardware.</li> </ul> <ul> <li>If you are a software company looking to offer existing application as a SaaS online service, AppLogic makes it possible to deploy the service in under a month, avoid the risk and expense of re-engineering the application, and scale it to hundreds of servers incrementally as demand develops.</li> </ul> <ul> <li>If you are an open source developer looking for a better way to monetize a popular application, AppLogic makes it easy to gain access to millions of new users who don’t use open source today simply because they lack the skills, the time or the desire to set it up and manage it. <a href="topic/how-about-applogic#top">Top of Page</a> <h3>When to use AppLogic?<a name="when"></a></h3> <p><strong>Deploy applications on standard infrastructure</strong><br /> If you’re developing software and don’t enjoy configuring servers and infrastructure, AppLogic makes it easy to deploy scalable web applications without dedicated IT personnel. Pick a standard infrastructure component from the catalog, copy your HTML files, scripts code and database onto the logical volumes and start your application.</p> <p><strong>Develop new web applications</strong><br /> AppLogic saves you time and aggravation when building and testing your application with the exact middleware and system configuration it’ll have in production. Simply copy and start one of the standard infrastructure applications that come with AppLogic and in minutes, you’ll have a private N-tier application setup and running. Run it in “sandbox” mode to fit even large application on a single server during test, or use a larger grid to test your code under real-world loads at any time.</p> <p><strong>Build custom N-tier application infrastructure</strong><br /> AppLogic is the ultimate tool for designing, building and replicating complex distributed infrastructures. With the visual infrastructure editor and catalog of virtual appliances, you can assemble, configure and troubleshoot your system visually. Integrations that took weeks can be done in hours. What’s more, AppLogic makes it easy to pre-assemble frequently used subsystems, such as clustered databases, web tiers, application server clusters, and many others, and reuse these assemblies in many applications, or in several places within the same application.</p> <p><strong>Test and tune N-tier applications</strong><br /> AppLogic’s monitoring system makes it easy to visualize what’s happening in your application under load, so troubleshooting and performance tuning are easier than ever before. You can also save a “known good” state of the application for rollback and literally check your application into a version control system to have complete visibility into all changes made to its infrastructure, configuration or code.</p> <strong>Achieve easy multi-tenant deployment</strong><br /> AppLogic enables multi-tenant deployment of existing web applications without expensive re-engineering. Simply run multiple instances of the application on the same grid and scale each individual instance as required, from a fraction of a server up to dozens of servers. As a result, most applications can be deployed as online services within a week or two avoiding the complex task of building and running a single huge multi-tenant application. <p><a onclick="JavaScript:window.open('http://3tera.com/demo.php', '3terademo', 'resizable=1, width=1170, height=760');" href="http://3tera.com/demo.php" target="3terademo"> Watch the demo to see how cloud computing can change your business.

Each server has two Ethernet ports, a gigabit port which is connected to a network that forms the grid backbone, and a second port connected to the rest of the datacenter and/or the public Internet. The backbone network is private, secure and provides non-blocking gigabit connectivity between any two servers.</p> <p>A standard AppLogic software image is installed on each server before adding it to the grid. One of the servers is designated as a grid controller and runs the management portion of the system. The operator manages the grid by accessing the controller through a secure browser connection.</p> <p>You can use almost any commodity server in an <strong>AppLogic</strong> grid. They must have at least an Intel P4 or a compatible AMD processor running at 1GHz or better, at least 512MB of RAM, 80GB of ATA/SATA storage one gigabit Ethernet interfaces for the backbone and another Ethernet interface for the public network. When running web applications, larger hard disks and more memory generally improve performance more than raw CPU speed. Shared storage, such as SAN, NAS or a common file system is not required – AppLogic implements a shared, mirrored storage pool using the hard disks of the servers in the grid.</p> <p>For efficient operations in hosting environments, AppLogic can be configured so that as many as 32 separate, independent AppLogic grids share the same backbone network. This makes it easy to implement “virtual private datacenters” using reasonably-sized (and priced) gigabit Ethernet switches.</p> <p>Finally, since AppLogic distributes applications automatically and dynamically across the grid, it is not necessary to use enterpirse class servers when building AppLogic grids. Due to factors such as limitations on memory bus and peripheral bus throughput, a larger number of commodity servers is quite likely to outperform a similarly priced grid built from higher-priced machines.</p> admin on "Dynamic Appliances" http://forums.domaingurus.com/topic/dynamic-appliances#post-90 Tue, 21 Apr 2009 16:27:47 +0000 admin 90@http://forums.domaingurus.com/ <h1>Dynamic Appliances</h1> <h3><br />How do Dynamic Appliances work?</h3> <p>AppLogic replaces expensive and difficult to integrate IT infrastructure such as firewalls, load balancers, servers and SANs with pre-integrated and pre-tested virtual appliances. Each appliance runs in its own virtual environment that boots it’s own Linux OS and appears as a separate physical server to the software that runs inside the appliance. AppLogic’s catalog appliances are built using leading open-source infrastructure like Fedora Linux, Apache, MySQL, JBoss and many others. Users can modify catalog appliances or build their own appliances from scratch.</p> <h3>Some Examples</h3> <p>One of the first Dynamic Appliances 3Tera has created is called BCK; it is their backup enabler <strong>Dynamic Appliance</strong>. You simply dragging a copy of BCK into an AppLogic application and then setting the schedule, number of backup copies to keep, and the backup location. The application will now be able to carry out its own backups with no operator intervention. It really is that simple.</p> <p>Another powerful concept in Data Center management is the Patch Management Dynamic Appliance. This appliance manages the roll-out and roll-back of new virtual appliance code by monitoring the versions of appliances in the AppLogic catalog and comparing those to the versions of the appliances in your application. If a catalog update is detected you are prompted to confirm the upgrade. When the upgrade is finished the Patch Management Dynamic Appliance will automatically restart the now up to date appliance.</p> <h3>Portability</h3> <p>An important feature of Dynamic Appliances is their portability. When you make a copy of an applications or move it to a different data center (yes, all of this is possible with a single command in AppLogic), the new copy of the application preserves the operational capabilities on the Dynamic Appliance.</p> <h3>What can I do with Dynamic Appliances?</h3> <p>More or less anything you can think of. One of the most advanced concepts is the MIG Self Migration Enabler. This Dynamic Appliance enables AppLogic applications to take snapshots of themselves and migrate from one AppLogic grid to another automatically. This solution could be used in conjunction with the Power Saver Dynamic Appliance to free up the energy demand at one data center by dynamically and automatically moving AppLogic applications to an AppLogic grid at another data center.</p> <h3>Can users create their own Dynamic Appliances?</h3> <p>Absolutely! 3Tera provides all of the technical documentation and libraries required to implement custom Dynamic Appliances. They are even making the source code of all of their own Dynamic Appliance such as the Backup and Power Saver Dynamic Appliance available as examples to be built on and extended.</p> <h3>The future of Dynamic Appliances</h3> <p>3Tera envisions a whole range of standard Dynamic Appliances that will be available in the AppLogic appliance catalog that will make data center operations much simpler and easier. Combined with customer and consultant generated Dynamic Appliances we see a new era in data center operations emerging. This is 3Tera’s vision: A self managing virtualized data center infrastructure that makes configuration, provisioning, and management far more efficient and effective than it is today. 3Tera’s Dynamic Appliances are a key step in this evolution.</p> admin on "AppLogic Interface" http://forums.domaingurus.com/topic/applogic-interface#post-88 Tue, 21 Apr 2009 16:01:28 +0000 admin 88@http://forums.domaingurus.com/ <h1>AppLogic – User Interface</h1> <p><br /> To achieve true utility computing, operators must have as much (or more) control of applications running in their virtual private datacenter as they have today in colo or in their own facilities. This requirement makes the user interface a critical component of the system. It must be both intuitive and powerful. AppLogic’s primary interface is an AJAX based system delivered via a browser. The interface is visual and highly interactive, with the look and feel of a desktop application. Designing infrastructure within AppLogic has the feel of diagraminng on a white board – but with the addition of a “run” button. For power users, all system functions are also available through the command-line interface, making it easy to write automation scripts and integrate AppLogic with datacenter management systems. The user interface of AppLogic consists of the following major components:</p> <ul> <li><a href="applogic-interface#dashboard">System dashboard</a></li> <li><a href="applogic-interface#editor">Infrastructure editor</a></li> <li><a href="applogic-interface#monitoring">Visual monitoring console</a></li> <li><a href="applogic-interface#commandline">Command-line interface</a></li> </ul> <h3><br /></h3> <h3>System Dashboard<a name="dashboard"></a></h3> <p>The dashboard is a web application that displays the configuration and current status of the grid, and allows the user to start, stop and manage applications. In the next release, the dashboard will also support functions like log viewing, add/remove/manage servers, manage users, etc. The dashboard is accessed by pointing a browser at the IP<br /> address of the grid controller.</p> <p><img src="http://www.domaingurus.com/images/applogic-dashboard.png" alt="AppLogic Dashboard" /></p> <h3><br /></h3> <h3>Infrastructure Editor<a name="editor"></a></h3> <p>The editor is a web application that allows you to visually assemble virtual infrastructure, create custom virtual appliances, manage catalogs of appliances and configure applications. screen shot of AppLogic Monitoring tools.</p> <p><img src="http://www.domaingurus.com/images/applogic-editor.jpg" alt="AppLogic Infrastructure Editor" /></p> <h3><br /></h3> <h3>Visual Monitoring Console<a name="monitoring"></a></h3> <p>The monitoring console is a web application that allows you to build a virtual network operation center by configuring, saving and displaying custom monitoring screens. The console combines run-time data for hardware, resource use and network traffic by application and appliance, as well as software-specific counters from inside virtual appliances such as the Linux /proc file system, Apache, MySQL and many others.

Each appliance runs in its own virtual environment that boots it’s own Linux OS and appears as a separate physical server to the software that runs inside the appliance.<br /> AppLogic’s catalog appliances are built using leading open-source infrastructure like Fedora Linux, Apache, MySQL, JBoss and many others. Users can modify catalog appliances or build their own appliances from scratch.</p> <h3>Disposable infrastructure</h3> <p>Infrastructure is assembled visually and stored as part of the application in AppLogic. The infrastructure is essentially disposable; it’s instantiated on the grid when the application is run, maintained while needed, and disposed of when the application exits.</p> <h3>Packaged distributed applications</h3> <p>AppLogic packages all code, data and infrastructure required to run a scalable web application into a single logical entity that can be started, stopped, managed, copied or even exported to another grid without modifications. By managing all interdependencies within the application, AppLogic leaves the user with a single logical entity that is easier to manage than most desktop applications. AppLogic includes several popular open-source applications such as Bugzilla, Twiki, SugarCRM and Zimbra. These applications are pre-integrated and ready to run.</p> <h3>Single point of management</h3> <p>AppLogic aggregates commodity servers into a scalable grid that is managed as a single system using a browser or secure shell. You can add or remove servers on the fly, as the gird is running, monitor the hardware, manage user credentials, reboot servers, install software, build virtual appliances, backup the system, repair damaged storage volumes, inspect logs and perform all other management tasks from a single point of control, all while the system is running. With AppLogic, managing a 48-server grid and a 2-server grid takes approximately the same effort.</p> <h3>Application scaling</h3> <p>AppLogic applications are fully virtualized and can be scaled easily from a fraction of a server to many servers. For example, the SugarCRM application included with the system scales from 30% of a CPU and 380MB of RAM to 7 CPUs and over 5GB of RAM without modifications. When starting an instance of an application, the user specifies the amount of system resources to be assigned to the particular instance within the limits set by the application integrator. Depending on the amount of resources specified, multiple instances of an application may run on a single server, while another instance of the same application may span multiple servers.</p> <h3>Operations monitoring</h3> <p>AppLogic includes a sophisticated monitoring system that provides unprecedented visibility into the operation of the web applications running on the grid. The system combines runtime information from the hardware, the virtual infrastructure and the applications themselves and makes this data available to the operator through an intuitive visual interface. You can monitor the use of system resources per application, virtual appliance or server, plus network traffic on each logical connection, as well as many software parameters from popular packages such as Apache, MySQL and others. You can also create and monitor custom counters that are computed from a combination of other counters, as well as set alarms on each counter.</p> <h3>High availability</h3> <p>AppLogic implements many features that improve availability of the system and the applications that run on it. These range from storage mirroring across multiple servers which ensures that a server failure never results in data loss, to the ability to recover from a failure of the grid controller, to high-availability features built into the catalog appliances. The ability to easily run two identical instances of the application on the same grid, or in different datacenters, provide the ultimate approach to high availability, in which a hot standby of your entire application is always available to take on the user load, should the primary instance of the application fail.</p> <h3>Resource metering</h3> <p>AppLogic has a built-in system for metering the resources used by each application. The system tracks and reports all significant events in the application lifecycle at which hardware resource use can increase or decrease, and the exact amount of memory, CPU and bandwidth assigned to the application on each of those events. The metering system is intended to serve as a foundation for sophisticated utility computing billing systems that make it easy to bill users for the exact amount of resources they consume.</p> <h3>Automation and integration</h3> <p>AppLogic comes with a powerful command-line interface that is fully scriptable and easy to integrate with datacenter management systems. In addition to scripts that control the operation of AppLogic, the interface makes it easy to intercept logical events such as server failure or reboot, start and stop of an application or appliance, failure of an appliance, intrusion detection and many others. Whenever such an event occurs, AppLogic runs a user-defined script that can take corrective actions and/or report the event to an external management system. For example, it is easy to write a script that restarts a failed appliance, or, alternatively, redirects the Internet traffic to a hot standby copy of the application and sends e-mail to the operator.</p> <h3>Run existing applications</h3> <p>Almost any existing multi-tier Linux application can run on AppLogic.</p> admin on "Cloud Computing With AppLogic" http://forums.domaingurus.com/topic/cloud-computing-with-applogic#post-86 Tue, 21 Apr 2009 15:53:04 +0000 admin 86@http://forums.domaingurus.com/ <h1>Cloud Computing With DomainGurus And AppLogic</h1> <p><br />AppLogic is a grid operating system which enables cloud computing for running and scaling web applications.

It uses advanced virtualization technologies to be completely compatible with existing operating systems, middleware and web applications. Billions of lines of tried and true infrastructure software, middleware and application code can be used with AppLogic unaltered.</p> <p>With AppLogic you can package an entire N-tier application or service into a logical entity and manage it as a single system. To make this possible, AppLogic captures and operates on the logical structure of the application. This approach also makes it very easy to assemble, deploy, monitor, control and troubleshoot applications visually in a browser.</p> <p>Each application includes everything needed to run on a grid of commodity servers. That’s why applications running on AppLogic scale from a fraction of a server to hundreds of servers and can be replicated on demand, deployed over and over again on the same grid or in multiple locations without modifications.</p> admin on "Grid Utility Hosting On The Cloud" http://forums.domaingurus.com/topic/grid-utility-hosting-on-the-cloud#post-85 Tue, 21 Apr 2009 15:38:52 +0000 admin 85@http://forums.domaingurus.com/ <h2>Grid Utility Hosting On The Cloud</h2> <p>There, now that we have all the “buzzwords” out of the way, we can get to the business of it all.
