High Availability

Highly Available Solutions Comparison

 

High Availability For Everyone

 

Since we’ve begun offering our High Availability (HA) Dedicated Servers, we’ve received a lot of questions about how they compare to traditional highly available solutions. Since these aren’t platforms the average Small-to-Medium Business (SMB) has the staff to design, develop, and deploy, many aren’t familiar with the nuts and bolts of these types solutions. Thus, we’re here to clear-up potential points of confusion and delineate the differences between the various HA options out there.

The average HA Solution generally consists of two or more servers clustered together, configured with data replication, with the traffic being directed by some form of DNS failover or load balancing software/hardware. In some cases these deployments are designed specifically for failover, and other times they are configured for load distribution (a.k.a load balancing). Though failover solutions tend to be the more simplified of these two options, they’re only marginally less difficult to configure and support. Since there are a variety of ways to approach failover and load distribution solutions, we’ll be focusing specifically on failover-based HA deployments — like the ones illustrated below.

In reality, neither of these options are simple — neither the solutions nor the costs — but why isn’t there an easier way? Why isn’t there a way that allows the average Linux, Apache, MySQL, and PHP (LAMP) stack user to just do what they do best, without cumbersome configurations and excessive cost structures? Why do you have to recode your applications to a different platform?

The answers to these questions can be involved, but the basic gist is, the technologies at the heart of traditional hosting solutions weren’t designed to coordinate multiple instances. As a result, they don’t work cooperatively or intelligently to ensure data continuity.

Until now.

ServInt’s new HA Dedicated Servers take the difficulties of complex configuration and cost factors completely out of the equation. We’ve engineered our High Availability Servers to handle the replication, instancing, and failover behind the scenes. You manage your sites and applications, and we make sure it’s always online. And in the unlikely event your server’s hardware ever fails, we replace it in less than 60 seconds — data intact. The best part is there’s no need to recode your applications or learn to administrate some unfamiliar platform.

 

HERE’S HOW THE MAGIC WORKS

By using our SimpleScale™ technology, we’re able to restore your server instance and its data to new hardware in under a minute. We do this by storing several copies of your data across our HA Server Clusters, and propagating that data to your new server’s hardware. It looks and works like magic, but it’s far more than sleight of hand.

Let’s face it, when you’re investing in an “always on” hosting solution, you’re basically paying for resources and redundancy you hope to never use. Fortunately, now you don’t have to — we’ll keep the spare hardware on hand — even though you may never need it.
