There is an ongoing discussion (read:argument) around something that is like the Voldemort of technology: vendor lock-in.
This blog kicks off a series of blogs in which we share some of the results from our State of Performance in Modern Applications Survey.

Last week approx. 65,000 IT professionals and executives converged on to Las Vegas for the most significant cloud event in the world: AWS re:Invent. It is hard to describe the spectacle, noise, excitement, and energy at the event.
Let me start by giving my one line view of the reason for the uprising in awareness of microservices, containers, SDN and the ever-present SDDC (Software-Defined Data Center): This is about agility, not speed.

Few people will argue that public clouds haven’t dramatically changed the industry in the past few years. There has been a tremendous increase in popularity of public cloud services such as Amazon AWS and Microsoft’s Azure, and the demand keeps growing every year.

A recent blog post from VMware’s CTO office discusses "DRS Pairwise Balancing", an allegedly improved version of DRS in vSphere 6.5 and later. "This new feature", the blog proclaims, "is needed as clusters keep on growing larger and larger." Turns out that some statistical measures used by old DRS became "statistical outliers" in larger clusters, that according to VMware "simply disappear as noise due to the vast number of hosts that experience far lower utilization” and thus fall "below the threshold required to trigger load balancing.”
On November 6, Amazon announced a new discount model called Savings Plans. We’ll review the changes and benefits in just a moment but before we jump into the details, let’s review the complexity to manage “legacy” reserved instances so we fully understand how much of an improvement this is for AWS users.
