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 […]

Ignore the hysteria, Cloud Foundry is just fine

stay-calm-at-work-desk

Recently, Rishidot analyst Krishnan Subramanian proclaimed the Cloud Foundry, Platform-as-a-Service (PaaS) cloud, had met its demise as a standalone platform. Really? That’s news to me, and I cover Cloud Foundry like paint. What got Subramanian so frazzled was Cloud Foundry started offering Docker in place of its own container runtime, Garden. And at the recent […]

Bridging the gap between AWS Lambda and other clouds: TriggerMesh

bridging-the-gap

If you want to do serverless computing today chances are you’re using Amazon Web Services (AWS) Lambda. Which is fine if you’re wedded to AWS, but if you’d rather use another cloud or run a hybrid cloud, AWS-specific Lambda may not be ideal. Enter TriggerMesh Knative Lambda Sources (KLASS), which offers a way to bridge […]

Financial services are embracing multi-cloud

hybrid-cloud

Multi-clouds — environments made up of multiple public and private clouds typically used for different purposes — may well be the cloud of choice for banks. That’s according to an independent report by 451 Research, ‘Multi-Cloud Fundamental to Financial Services Transformation.’ I’m not here to argue. This report, which was sponsored by Canonical — the […]

What’s the difference between containers and virtual machines?

question-mark

I was at a conference recently when I realized the person I was talking with thought that containers were just smaller versions of virtual machines (VM). Ah, no. No, they’re not. Yes, they can function in the same ways from a practical viewpoint. For example, they’re both commonly used to run server applications. How they […]

CoreDNS: The DNS for cloud-native computing

DNS

I have a t-shirt which reads, from top to bottom: “It’s not DNS. There’s no way it’s DNS. It was DNS!” As every sysadmin knows, all too many network problems boil down to a Domain Name System (DNS) blunder. That’s already annoying, but when you have to deal with a DNS headache with fast-moving containers […]
