Okay, so here’s something different to reflect upon. By now we all know the benefits that cloud computing brings and how it promises to be a game-changer in the days ahead. However despite all the buzz surrounding cloud computing, a nagging concern remains – who will ultimately be held responsible if the cloud flounders for whatever reasons? The accountability word hangs like the proverbial Damocles sword on any potential cloud customer.
There are several factors that have an impact on the availability of services, mostly related to infrastructure failures. Failures are not only related to unrecoverable hardware outages, but also to recoverable OS or middleware failures.
In today's dynamic environment, new thinking is required when it comes to security, especially because the infrastructure is more abstract and less defined, everything needs a web interface, agents and heavy clients are not acceptable, and traditional defences no longer apply.
Note: Through the end of the year, we’ll be posting one blog per day from our top 10 “greatest hits” from Thoughts on Cloud since we launched in September. This post is #8 and was originally published on Nov. 16.
This is the second part of the IBM SmartCloud Enterprise+ blog entry with details about the service offering, features and functions, migration strategy to move workloads into the environment, and more interesting things that IBM is planning to add in the near future.
The major providers in the cloud space, such as Amazon, Rackspace, and IBM, include resiliency mechanisms that ensure data is not lost in the case of an infrastructure outage, at least to satisfy the levels of business continuity established in their service level agreements (SLAs). Some cloud providers also offer services that give users the ability to create private images, and snapshots of the instances and storage they provisioned for added safety from data loss. However, none of these prevent database outages.
