DevOps is The New Black!

"DevOps" has been around as a buzzword in tech sector for almost 10 years now. "DevOps Professional", "DevOps Technology", "DevOps Engineer", "DevOps Practices" are few such words that have become ubiquitous with software technology. Wikipedia defines "DevOps" as "a set of practices intended to reduce the time between committing a change to a system and the change being placed into normal production, while ensuring high quality." DevOps is The New Black! My first encounter with "DevOps" was six years ago when I worked for an investment bank and worked as a "release and configurat...

How Hybrid Cloud Costs Can Spiral Out of Control

If you listened to the analysts 10 years ago, we should by now be consuming all of our IT from the cloud, much like we consume electricity from the grid, with little knowledge or care as to how it is generated or distributed. Things haven’t quite moved at that pace and we are stuck, possibly for many decades to come, at the mid-way point: hybrid cloud. Hybrid cloud, or a computing environment that mixes on-premises infrastructure, with public cloud and SaaS applications, has become the norm that’s replaced or augmented the data centre or the server room. If you’re like most organisations...

Serverless Computing

The name alone “serverless computing” can generate excitement from Developers, System Administrators and Management. No more servers? Less overheads in managing infrastructure, less operational expenditure, perfect! Let’s start with what IS serverless computing. Serverless computing is the ability to run code or to execute functions using machine level resources without the responsibility of managing the servers that actually execute the code. The servers still exist, but the level of management and associated tasks such as capacity management is hidden from the serverless computing u...

What is Business Architecture?

Over the last couple of years there has been quite a buzz around business architecture. There are courses on business architecture popping up all over the place. Some good and some not quite as good, like everything! We will be going back to some basics to understand what business architecture is (well my view) and how it can be used, why you need it and what the benefits are of having a business architecture. We will not be going too deep but give you enough to understand and be able to make some decisions, if necessary. The first one being, how can I get a business architecture? Well, ...

About the Responsible Disclosure

For a while now, many companies and organisations have been trying to find a solution to counter the open bug bounty or to prevent the full disclosure of a security breach publicly. You may have already heard of the concept "Responsible Disclosure" which, takes the concept of “Full Disclosure” except this time, the discovery of the defect leaves time for the publisher to publish a patch. This process does not always run smoothly, as researchers usually want to warn the community of their discovery as quickly as possible and publishers often take a long time to propose a patch. During this ...

CPU Design Flaw

A fundamental design flaw in modern CPU chips has forced a significant redesign of the way the Linux and Windows kernels interact with hardware. Named Meltdown and Spectre, these flaws affect all computer systems, both private computers and corporate systems, including those used in cloud infrastructures. Both these design flaws could expose access to ultra-sensitive information. Meltdown is currently only present in Intel x86-64 processors whilst Spectre touches all modern processors, whether they are AMD, Intel, or even ARM. Meltdown breaks the isolation between the memory used by the us...

Improve your network service delivery time & accuracy through NSO

Through our work on automated service delivery, our customer’s investment in automation is tempered by network provisioning times that are often too slow and prone to error. They’re looking for ways to improve deployment and management of networking services due to changes in expectations regarding the speed and flexibility of IT services. Often network service configuration relies heavily on manual configurations based on “runbooks” and Operational Support Systems (OSS) containing static and hard-coded content. The processes can become stale and outdated due to incremental process cha...

Agile Project Management

In a fast paced world, speed to market is important. Traditional project management methodologies typically take a lot of time, effort and cost to plan and execute. With how fast technological improvements are being made, the end result, once deployed using a traditional project management approach, could see the technology being made redundant before it even reaches the release stage of a project. Agile gets around this by using an iterative release approach. The Manifesto for Agile Software Development, commonly known as the Agile Manifesto outlines the core values of Agile project manageme...

Do I Still Need My Data Centres?

This should be a question that any corporation utilising large spaces of data centres can now ask themselves knowing that there is a more than suitable alternative solution. Large and complex overheads are always associated with data centres. Just getting a piece of hardware in, configured and online can sometimes take weeks or in some cases months. At some stage that hardware will need to be upgraded or replaced, which means more labour and paperwork. What happens when you need to expand and your allotted space is full? Even more complicated networking and hardware placement in a different ar...
