The (hyper)converged revolution
of compute and storage
Thanks to the rise of flash storage and the commoditization
of the compute and storage layers, recent years have seen the
tremendous rise of hyperconverged infrastructure. In such
an environment, storage and compute — servers — are collapsed into a single unit of infrastructure, effectively eliminating expensive and complex SAN environments.
Hyperconverged infrastructure enables organizations to
easily manage and scale their datacenter environments. This
architectural option has been a boon for many customers
because it’s enabled far easier administration of the datacenter and has led to decreased costs and increased end‐user
and customer satisfaction.
Modern application architectures
If you’ve never heard the phrase bimodal IT, here’s a quick
rundown for you: IT has dueling priorities these days. First,
organizations have a reasonable expectation that IT will
continue to support what might be considered “legacy applications.” In reality, such applications likely will continue to
be mainstays of the business foundation for the foreseeable
future. These hardy survivors include client/server enterprise
resource planning (ERP) systems, collaboration systems, and
local database applications.
These applications traditionally have required a conservative
approach to maintenance. As mission‐critical applications,
they need a rock solid foundation, high availability mechanisms, and a light touch when doing updates, which must be
painstakingly planned. The goal is to reduce risk to the business by ensuring that crucial applications are always on. The
need to minimize risk to these applications is one of the reasons some IT departments have reputations of being stodgy
and unyielding. In fact, the IT group is simply trying to keep
the business running. Change makes that a difficult charge.
On the flip side of the equation, a new breed of applications is
popping up. These innovative application types might exist in
