Recently I’ve been asked why switch-case statements should be avoided, it turns out to be a pretty common question, and although I’m pretty happy with the reasoning of switch statements being less readable and maintainable, I had forgotten the source of this wisdom so I thought it would be worth revisiting.Read More »
I first heard of the term “serverless” in about 2015, probably around the time that the “Serverless Framework” launched, October 2015.
I next heard about “serverless” about a year later, only this time, it was used on the much broader topic of “Serverless Computing”, around June/July time there seemed to be a huge push from InfoQ on this topic, in particular at QCon London.
According to many, the concept of “serverless” really only became a reality in 2014 when Amazon Web Services (AWS) launched their functions as a service (FaaS) “Lambda” service, allowing you to run Node.js code in the cloud on demand, without really any knowledge or care for the servers they run on.
Around 2016 there was lots of talk of FaaS (functions as a service), PaaS (platform as a service), and the benefits of the serverless architecture, which was really encouraging and began to feel like it was ready for “prime time”.
In November 2016, I wrote an article entitled “Will the last person to leave turn the LAMP off?”, which was a play on words, a nod to serverless and an introduction to the concept of “stackless”.
Think about it, the “stack” is becoming less important; who cares about what hardware you’re running, platform you’re on, service you’re using, or even operating system, so long as it does what you need it to do.
Gone are the days where you need to buy or rent part or all of a physical server in a data centre somewhere, perhaps near to docklands London, as is financially viable. The concept of “serverless” only helps to cement this idea.
So when it came to rewriting a legacy API the idea of using AWS API Gateway and Lambda felt like it might be the right way to go. Read More »
There’s a number of companies that have been pioneering the microservices architectural style, including Amazon, Netflix, The Guardian, the UK Government Digital Service and comparethemarket.com. But is it living up to the hype?
“Microservices is a label and not the description” - Martin Fowler
You can think of Microservices much like Service Oriented Architecture (SOA), an architectural approach, rather than a technical implementation, like Enterprise Service Bus (ESB).
It is therefore not a silver bullet and it’s easy to get things wrong.Read More »
Why does the agile software development exist? What’s it all about? Why do people use it? Who uses it? How do you use it?
It’s about communication and flexibility, delivering business value sooner, breaking work down into manageable chunks and even automated testing.
It’s a way to provide businesses with the discipline and focus needed to maintain agility and sustainably deliver customer value.Read More »
Bring your own device (BYOD) refers to the policy of permitting employees to bring personally owned devices, like your mobile phone to their workplace and using those devices to access and use company information, such as email.
Employees have been bringing their devices to work for quite some time, but by around 2012, it had become clear that every organisation needed a policy that would outline whether you could bring your own device or indeed not. However, these days, it’s less likely and even considered counterproductive to have such as prohibitive policy which means having a more comprehensive policy that incorporates the realities of modern technology and usage.Read More »
