What is a grid?
A grid is a hosting platform that’s powered by large numbers of servers. This gives you access to a large pool of resources, such as processing power, memory and storage space.

Why do I want to run on a grid?
With AppLogic it is easy to scale and manage the infrastructure for your applications. Because AppLogic runs on a grid of standard commodity servers, you can:


  • Deploy existing web applications on the grid without changing any code
  • Run multiple different web applications on the same server
  • Scale each application from a fraction of a server up to the whole grid
  • Manage whole racks of servers easier than a single server today
  • Handle hardware failures automatically without losing data
  • Add or remove servers and storage without disrupting applications
  • Manage all applications, servers and storage with just a browser


AppLogic does not require a SAN or other expensive hardware, and is open and vendor-neutral. 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.

Will these grid servers function like my dedicated server?
Yes – you get full root access to the appliance on the grid. This includes root, or even WHM/cPanel access just like any other dedicated server.

How is a grid server different from a regular server?
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.

What kinds of sites can I host on your grid?
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.

Can I host multiple websites on the same grid server?
Absolutely! We even offer grid servers with cPanel, so that you can easily create and manage multiple domains.

Can additional bandwidth, storage and RAM be added?
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.

What happens when you run out of space on your grid?
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.

What about backups and security?
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.

What happens if a grid server crashes? Does the whole grid fail?
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.

Can I bind multiple IPs to the same grid server?
Of course! In fact, each domain on a grid server can have its own IP address and SSL certificate.

What kind of systems would I need to purchase from you now to support all my clients?
You can start off with the Cumulus plan and scale out from there.
Back to Top



How many nodes can I scale to?
256 Nodes (1,024 Cores). If you need more than this, nothing is stopping you from purchasing more grids and networking your grids into your own cloud.

How much will this cost me?
Wrong question. The right question is how much will I be expected to invest?

What is the length of the contract?
There is no long-term contract and all packages are billed upon a thirty (30) day / monthly utility, billing cycle. You are not locked into any long term contract and can enjoy the flexibility of paying for what your requirement are.

Is there any incentive or pre-payment discounts that I can apply?
