As you consider a career in IT service management, you might be wondering, “What is ITIL certification? And is it worth pursuing?” Understanding ITIL certification and its potential benefits can be worthwhile for your professional development.

Networks are complex systems with many components that can impact performance and security. Factors such as bandwidth, latency, packet loss, and device configurations all play a role in how well your network functions. Additionally, external elements like internet service provider reliability, cyber threats and even physical hardware conditions can affect network performance.

We recently explored what the cloud is and how it has evolved over 60 years. Yet, cloud computing emerged into what it is today in 2002, when Amazon, the e-commerce giant, sought a more efficient way to expand its online marketplace. So, it is not surprising that the company’s cloud services subsidiary (AWS), which launched in 2006, is the largest Cloud Service Provider (CSP) today. This CSP marketshare guide shares the details of the cloud infrastructure market, the dominant players, and more.

The trend continues to accelerate – even faster now. Cloud computing was already booming before 2020. But in the following two years, remote work flourished, and cloud adoption soared.

Yet there’s more to the rise and rise of cloud computing than remote working.

As an example, while Savings Plans are applicable to both EC2 and Fargate instances, RIs are only applicable to EC2 instances.

It’s a bit like going to the gym, lifting weights, and seeing real results, only to realize that you no longer fit into your old clothes. Now you have to decide if you want to modify them or buy new clothes. We can use this very simple analogy to understand the differences between horizontal and vertical scaling.
