Cloud Paradigms

  • FaaS: Function as a Service (FaaS) is a more extreme take on the PaaS paradigm since it not only assumes a given programming language but it also abstracts away from the program’s entry point. For example, in a regular PaaS, the programmer has to provide the embedded HTTP server for a microservice, whereas in a FaaS platform, the HTTP is implemented by the platform.  (01/01/2019)

  • HCI: Hyper Converged Infrastructure (HCI) is characterised by being fully software-defined and by virtualising all elements of the stack (compute, storage, etc.). It is a term increasingly used by Cloud vendors to define their on-prem solutions wherein “convergence” is, naturally, with their cloud native offerings.  (06/01/2020)

  • IaaS: Infrastructure as a Service (IaaS) abstracts away from the hardware (blades, racks, storage devices and so on) but it typically leaves operating system installation and further software-related concerns to the customer.  (01/12/2019)

  • PaaS: A Platform as a Service (PaaS) offering typically involves an application server (or runtime environment) so that the customer is only responsible for providing high-level software artefacts such as JAR files in Java or DLL assemblies in .NET. It is appropriate for monoglot teams targeting one of the PaaS' supported languages who write functionally-rich rather than performance-tuned code; this is because compiling custom kernels or tuning the underlying runtime environment (e.g. JVM heap settings) is typically beyond the intended level of abstraction conceived under the paradigm.  (01/02/2018)

  • SaaS: Software as a Service (SaaS) typically refers to third-party services that can only be used in a cloud fashion, such as SalesForce or Expensify, or that offer a choice between SaaS and custom installation (be it on-premise or in the cloud) such as Atlassian Confluence. In this sense, SaaS is a model for third-party vendors for offering one’s software to customers rather than a workload abstraction level such as IaaS, Paas, and FaaS.  (01/10/2019)

  • Azure: Azure, Microsoft’s cloud services division, may appear to be a cloud for “Microsoft Windows” software but this is a misconception since it has a clear Linux-first strategy.

  • Rackspace: Rackspace was a traditionally hosting provider that is trying to reinvent itself as a cloud alternative to the big three.  (01/01/2018)

  • RedHat OpenShift: OpenShift is RedHat’s answer to the need of a commercially supported Kubernetes implementation for on-premise (private cloud) use cases.

Content Delivery Network (CDN)

  • Akamai: Akami introduced a CDN offering to the marketplace years before cloud computing (e.g. AWS) was a reality. Today it suffers from extreme competition from vendors that also are strong in their security offering like Cloudflare as well as from the convenience of using CDN services native to a given cloud such as Amazon CloudFront.  (01/02/2018)

  • Amazon CloudFront: Amazon CloudFront is the default option for AWS-based services since it can be instrumented programatically. However, in a multi-cloud or public/on-premise scenario, it may be a less attractive option.  (01/12/2019)

  • Google Material Design Lite (MDL): Google Material Design Lite (MDL) is focused on implementing the Material Design principles in terms of user experience and look & feel. The emphasis here is arguably less on the responsive aspect compared to Bootstrap.   (01/03/2018)

Web Style Sheet Processors

  • Block Element Modifier (BEM): Block Element Modifier (BEM) is a convention (rather than a library) for making styling more manageable, encapsulated, and reusable.  (01/03/2018)

  • CSS: Cascading Style Sheets (CSS) is the mechanism to add styling to web documents supported by all web browsers by default; however, developers seldom write CSS directly in modern web applications. This is because CSS is limited in terms of modularity and manageability; it is, thus, often generated using a pre-processor or applied directly using JavaScript-based component technology.  (01/05/2018)

  • Less: Less is a style language inspired by SaaS (it generates CSS files) that is written directly in JavaScript rather than Ruby. This allows to compile CSS directly on the web browser for development purposes. It is, arguably, slightly less feature rich than SaaS.  (01/02/2018)

  • Saas: Syntactically Awesome Style Sheets (Saas) is a style language that includes features such as variables, nested rules, and mixins. It generates CSS files.  (01/01/2019)
