SIOS Technology has announced the release of a new eBook, Step-by-Step: Configuring Amazon EC2 for Business-Critical Applications. The eBook examines what users need to do to prepare the AWS EC2 infrastructure to support business-critical applications clustered with Windows Server Failover Clustering (WSFC).
The eBook is written by Dave Bermingham, Director of Customer Success at SIOS. He is recognized within the technology community as a high-availability expert and has been honored to be elected a Microsoft MVP for the past 12 years: 6 years as a Cluster MVP and 6 years as a Cloud and Datacenter Management MVP.
AWS guarantees that if two or more instances are deployed in different availability zones (AZs), at least one of those instances will have external connectivity. The SLA does not guarantee that the application or service running inside the instance will be available. It only guarantees the availability of the instance itself. To address availability of the application, users will need to take additional steps to monitor the application and recover it should a failure occur. In the case of transactional replications like SQL Server and other relational database management systems (RDMS), users also have to ensure the data is replicated and available across each AZ. Depending on the application, this additional layer of application monitoring and replication will be accomplished by a combination of one or more of the following: load balancing, clustering and/or data replication.
In this eBook, Dave describes in great detail what is needed to prepare the EC2 infrastructure to support business-critical applications clustered with Windows Server Failover Clustering (WSFC). As learned in the SLA, in order to qualify for the 99.99 percent availability, instances must be deployed across multiple AZs. Readers will learn how to design EC2 infrastructure to support cross-AZ failover clustering.
