Diagrams as Code: The Complete How-to-Use Guide

We're seeing more and more tools that enable you to create software architecture and other Diagrams as Code. The main benefit of using this concept is that majority of the Diagrams as Code tools can be scripted and integrated into a built pipeline for generating automatic documentation. The other benefit responsible for the growing use of Diagrams as code to create software architecture is that it enables the use of text-based tooling, which most software developers already use. Furthermore, text is easily version-controllable and diff’able.

How Can Cloud Computing Architecture Initiate Beneficial Changes?

Let’s take it from the top and define what cloud computing is. It refers to data centers accessible over the internet to many users and is spread across various locations from a centralized server. Cloud relates to providing computer system resources such as data storage and processing power at request. Its architecture enables robust and scalable computation-intensive capabilities through on-demand delivery and the pay-as-you-go model. So, what is so beneficial about cloud computing architecture? Would it be any different for your business if just the internal structure were changed?

The Theory and Motive Behind Active/Active Multi-Region Architectures

The date was 24th December 2012, Christmas eve. The world’s largest video streaming service, Netflix experienced one of its worst incidents in company history. The incident was an outage of video playback on TV devices for customers in Canada, the United States, and the LATAM region. Fortunately, the enduring efforts of responders over at Netflix, along with AWS where the Amazon Elastic Load Balancer service experiencing disruptions resulting in the cause of the incident, managed to restore services just in time for Christmas. If one were to think about the events that ensued over at Netflix and AWS that day, it would be comparable to all those movies of saving Christmas that we all love to watch around that time of year.

This idea of incident management comes from the ubiquitous fact that incidents will happen. This is not an unknown fact and best immortalized by Amazon VP and CTO Werner Vogels when he said “Everything fails all the time”. It is, therefore, understood that things will break but the question that persists is can we do anything to mitigate the impact of these inevitable incidents? The answer is of course yes.

JAMStack CMS: Why and How To Use It

Introduction

Has it recently crossed your mind why so many businesses failed to respond to COVID-inflicted challenges? After the 2020 turmoil, they’re hoping to break even at best while suffering from significant customer churn and technology inconsistencies. However, only trying to retain your existing customers is not the best idea for business growth.

That is why unprecedented times make businesses start looking for nontrivial solutions to reach wider audiences. As customers are getting more mature in their digital-driven journey, companies have a harder time meeting the customer of today’s expectations. Given that face-to-face communication is not an option these days, the only medium for successful B2B/B2C interaction is your website content.

Easy and Fast Adjustment of Kubernetes CPU and Memory

Assigning and managing CPU and memory resources in the Kubernetes can be tricky and easy at the same time. Having done this task for numerous customers, I have decided to create a framework zone. I will show you what Kubernetes resources and limits are and how to manage them.

The framework contains the following steps.

  • Infographic Guide shows what algorithms to follow to determine and assign the resources and limits.
  • Code templates allow applying those algorithms with minimal adaptation.
  • Algorithms and tools to gather the metrics about resource consumption and set up the limits.
  • Links to the official documentation where you can quickly grab some examples and read more detailed information.

What This Article Doesn't Contain

My goal here is simplicity. So you won't find detailed descriptions of how resources, limit ranges, and quotas work. There are plentiful articles written about it, as well as Kubernetes thorough documentation. Instead, here you will find information on how to quickly start adjusting Kubernetes resources in your projects.

Breaking Down Serverless Anti-Patterns

Serverless adoption rates have been climbing ever since the technology was brought into the spotlight with the release of AWS Lambda in 2014. That is because serverless makes an offer that cloud developers simply can not resist, providing the following benefits:

  • Server management is abstracted to vendor
  • Pay-as-you-go model where you only pay for what you use
  • Automatically scalable and highly available

These benefits are achieved by the characteristics that define the technology. Serverless applications are stateless distributed systems that scale to the needs of the system, providing event-based and async models of development. This has worked in favor of the technology, resulting in a desirable solution for the cloud.

Provisioned Concurrency: The Silver Bullet to AWS Lambda Cold Starts

The year 2014 marked the start of the serverless era with Dr. Werner Vogels announcing AWS Lambda to an ecstatic crowd at AWS’ esteemed re:Invent. What was promised was a compute service abstracting away all the pains of cloud orchestration, thus leaving the user to only worry about the business logic they would run on these magic little worker nodes spun out of thin air and pure engineering.

Even though AWS Lambda was not the first FaaS service out there, with a startup called PiCloud being the first FaaS provider back in 2010, AWS was the first major cloud provider to jump into the race. In fact, it can be argued that AWS is actually the one that kick-started the serverless era, soon followed by Google Cloud Functions and Azure Functions by Microsoft. By 2017 the cloud wars intensified, with more and more providers descending upon the battlefield, all championing one promise, no more orchestration needed.
