Let’s say you are a company that is migrating SAP, Oracle or other business-critical applications on the AWS cloud. You may be doing this yourself or working with an implementation partner to ensure that everything goes smoothly. As a business, you depended on clusters with your on-premise applications to ensure that you achieved high availability.
High Availability for Cloud – What Does it Mean?
The term “High Availability” means many different things to many different people and can lead to confusion for those moving to the cloud. You will see all kinds of claims of uptime in the cloud, sometimes as high as 99.999% uptime, which means only 5.26 minutes of downtime per year. That sounds great in theory, but if you read the fine print, you will see that there are no guarantees and many exclusions. In practice, these lead to real downtime and real lost revenue for your business. All you need is one downtime event like the recent major cloud outage that took customers off line for way more than 5.26 minutes.
Without real high availability, you may be helpless until the cloud comes back on-line. In addition, you want a solution that not only protects you from failure, but also allows you to do maintenance and upgrades without downtime and to rollback in case of issues. You also want to avoid duplicating the same issues that brought your primary application server down propagating through to your secondary servers. It is up to you to make sure these scenarios don’t happen to you and that your high availability requirements are met.
SIOS Protection Suite for Linux Provides Real High Availability for AWS
While cloud providers like AWS provide availability options, they do not provide the level of high availability and breadth of protection across the whole application infrastructure that customers demand and that you achieved by using clusters before there were clouds. AWS customers know this and know that they need real availability and clustering software tools that provide actual levels of high availability (at least 99.99% uptime). That is why AWS is partnering with SIOS and our SIOS Protection Suite for Linux to achieve these desired levels of high availability for our mutual customers and the critical applications they are moving, to the AWS cloud.
SIOS Protection Suite for Linux provides a tightly integrated combination of high availability failover clustering, continuous application monitoring, data replication, and configurable recovery policies. SIOS Protection Suite for Linux includes SIOS LifeKeeper, SIOS DataKeeper, and multiple Application Recovery Kits (ARKs) to protect your business-critical applications and data from downtime and disasters.
SIOS Technology Collaborates with AWS to Provide Quick Start
To make the deployment of SIOS Protection Suite for Linux as easy as possible on the AWS Cloud, a Quick Start was created by SIOS Technology in collaboration with AWS. Quick Starts are automated reference deployments that use AWS CloudFormation templates to deploy key technologies on AWS, following AWS best practices. This Quick Start is for enterprise users who want to deploy SIOS Protection Suite for Linux on AWS into their test or production environment.
The SIOS Protection Suite for Linux on AWS Quick Start creates a high availability Linux cluster in a virtual private cloud (VPC) within a single AWS Region across two Availability Zones. It also supports out-of-the-box protection for SAP systems, Oracle databases, and other business-critical applications.
