Untangling the service mesh

service-mesh-metaphor

You may have noticed that, as you run more and more applications in containers it’s not easy to get them to talk and play well with each other. That’s because instead of monolithic applications using APIs to talk to components on one machine, we now have one app here, another there and they use networking […]

What is multi-cloud anyway and why do we use it?

multi-cloud-visualization

Many companies are moving to multi-cloud deployments. For example, most EMEA and North American financial services businesses are moving to multi-clouds within the next two years. Gartner reports 81 percent of surveyed public cloud users are already working with multi-clouds. But, Gartner states that multi-cloud is a subset of hybrid clouds. I disagree. In a […]

Kubernetes’s explosive growth has come with attention paid to security and stability

growth-concept

You may have noticed I write a lot about Kubernetes, the Cloud Native Computing Foundation (CNCF) sponsored open-source container orchestration program. That’s because I have no choice in the matter. Just like Docker turned containers into the way to run server applications, Kubernetes quickly overcame its rivals and became the way to manage containers.  Practically […]

Project Pacific: VMware’s new road from vSphere to the Kubernetes-based hybrid cloud

Pacific-Coast-Highway

Many people use VMware’s vSphere. How many? VMware claims there are over 70 million vSphere workloads running out there at any given time. That’s a lot of people running mainline business applications on VMware’s signature virtualization platform. That’s great, but how do you move those workloads to a cloud? VMware has an answer, re-engineer vSphere […]

How to avoid wasting money on under-used cloud resources

wasting-money-in-the-cloud

According to the research giant Gartner,  we’ll spend $206.2 billion on the public cloud. That sounds about right. But, at the same time, according to the cloud resource management company ParkMyCloud, we’ll waste up to $14.1 billion in cloud spending. By a ballpark estimate, that means you’re probably wasting 6.8 percent of your IT budget […]

What is AWS Aurora?

AWS-Aurora-question-marks

One of my first IT hats was as a DBMS administrator (DBA). I was a Datatrieve and xBase developer, who moved on to DB2. IBM DB2 was the first real relational database management system (RDBMS). While RBMSs aren’t as fashionable as they once were–it’s all NoSQL according to some of my friends–much vital enterprise work […]

How do you bundle a cloud native application?

bundle-of-ropes

On servers, we use packages like DEB and RPM to bundle software applications. With the rise of containers, we use Docker and CoreOS rkt to move and “install” our programs. But, now that we’re moving on to cloud native computing, how do you “bundle” a cloud native application? That’s a darn good question. A cloud […]

Are you really going to save money by moving to the cloud?

cloud-savings-piggy-bank

The number one reason most people move to the cloud is to save money. But, will you really? Sure you’re guaranteed to reduce your Capital Expenditure (CAPEX). But, if you’re not careful all you’ll end up doing is replacing your CAPEX expenses with cloud service Operating Expense (OPEX). So, before you sign the dotted line […]

Clouds and containers are not all about what’s new and hot

clouds-in-the-sky

This past Spring at London’s OpenInfra Days UK 2019, Mark Shuttleworth, executive chairman at Canonical and creator of Ubuntu Linux, said in a keynote, “I believe OpenStack is important. It’s become trendy to say: ‘I’m skipping OpenStack and going straight to Kubernetes.’ It’s like skipping salad and going straight to steam – they both solve […]

Avoid these five all-too-common cloud migration mistakes

avoid-mistakes-metaphor

I’m on the cloud. You’re on the cloud. We’re all on the cloud. But, as we move more and more of our IT — lock, stock, and two smoking servers — to the cloud, you should make sure you know what you’re getting into. Yes, the cloud can be a real help, but there are […]
