What’s serverless & can it save you money?

So now that we’re all finally starting to understand the corporate cloud, IaaS and even be able to weigh up the advantages and identify certain problems that arise from binning the hard iron, the boundaries are getting pushed a step further with serverless, the latest buzz word in IT disruption.

Understanding Serverless

Serverless you say, what’s that? “Serverless means you don't have to think about the servers that you rely on to deploy and run an application. The idea is for the servers to exist in the background, as a resource that scales up or down automatically, according to the application's needs.” a tidy definition supplied by this article in Channel Futures, which goes on to note: “In essence, serverless computing is a way of taking the Infrastructure-as-a-Service (IaaS) model to the extreme. Not only does serverless computing relieve you of the need to maintain your own infrastructure, but it saves you from the hassle of having to provision or administer infrastructure in any way.

Will AWS per-second billing really save you money?

[fa icon="calendar'] Oct 19, 2017 9:09:00 AM / by Sarah de Castro posted in AWS, Budget, Azure

The recent move  by AWS from a per-hour to a per-second billing model, for its Linux-based EC2 instances,  was only to be expected, reflecting the increasing demand for scalability in computing solutions. But at the end of the day will it really save you money? Could this increased flexibility in pricing create a too-relaxed attitude, amongst those responsible for procuring this expensive resource?

Our Faces: Xavier Garcia, co-founder & CTO

Part one of a two part interview series with tinkering whizz-kid and OneKloud CTO.

 

What’s up Xavier, can you introduce yourself?

I compiled my first Linux Kernel at eight years old. As a kid I used to disassemble just about everything I could get my hands on. At ten years old I modified the electronics of my first walkie-talkies to try to tune into the police frequency. Then I started coding, the first thing I did was was to clone my mom's cell-phone sim card so I could use her phone without her knowing. My second project was to clone the television’s satellite card so I could watch cable on my computer… I’ve always been into tinkering, fiddling. My studies were math/electronic oriented in high school and then I went on to an engineering school and then got a Masters 1 degree from the Dominican University of California, University in San Rafael, California. Today my whole house is totally controlled by computers, from the front door to the lighting and everything in between. I’m also a massive fan of raspberry pi and arduino.

Long distance relationships… how we make our global team work for us.

 I’m writing this from a small wooden room in a village called Pamparato at the foot of the italian alps, in Italy’s piedmont region. Today, my boss Eric is on a plane high above the pacific ocean. Xavier, co-founder and CTO is somewhere between France and Spain, and the others are either in the offices in Bordeaux (France) or San Francisco. We’re under the influence of the cloud, a hybrid model combining remote and local hubs, from international locations. Considering we are a small (rapidly growing ahem!) startup and not a multinational company, we’re spread pretty wide across a diverse global landscape.

The vendor landscape: navigating under the cloud

[fa icon="comment"] 0 Comments

The enterprise sourcing environment mirrors consumption trends of the digital age: it’s all about more, more complex requirements, more choice, more international, more specialist offers, and more time needed to evaluate, select, track and manage these relationships. With no choice in the matter, companies now need to rely on in-house expertise and their wits to contend with multiple vendors, hard-to decipher needs and offers.

The five challenges of capacity planning in the cloud

[fa icon="comment"] 0 Comments

Finding the optimal amount of resources needed to get the job done, and obtaining them at the most efficient cost a tradeoff between SLA, availability and cost? These eternal concerns of capacity planning experts are more relevant than ever, despite the dematerialization of many of a company's “resources” as computing power migrates to the cloud. The main attributes of the cloud environment: flexibility and scalability, rhyme with unpredictability. Capacity planning is confronted with a range of new challenges as the scope shifts from hard iron to IaaS.

Why cloud-based IT gives new relevance to capacity planning

[fa icon="calendar'] Jun 16, 2017 4:44:00 PM / by Sarah de Castro posted in AWS, Budget, Corporate, capacity planning, Predictive

[fa icon="comment"] 0 Comments

Just because  cloud infrastructure makes it possible for  businesses to adapt and scale their IT needs with more flexibility than ever before, doesn’t make it easy. While cloud migration is quickly becoming an indisputable step into the future, many companies are finding the transition comes with an unforeseen disadvantage: a debilitating lack of control and foresight.

“Capacity planning is the process of determining the production capacity needed by an organization to meet changing demands for its products. In the context of capacity planning, design capacity is the maximum amount of work that an organization is capable of completing in a given period,” says Wikipedia. So are these definitions and task frameworks relevant if we are talking about virtual IT? Absolutely.

The end of AWS tagging…  at last!

It’s funny when you think about it, cloud infrastructure provides us with the capacity to power and host the most cutting edge computing technology, allowing the latest scientific and technological innovations to go above-and-beyond, but the way in which AWS is managed and how it interfaces with developers and companies is really pretty dated.
