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 and WHM 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.
Back to Top
What kind of systems would I need to purchase from you now to support
all my clients?
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.

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.
