The popularity of using cloud computing services is explained by resource optimization, cost reduction, and increasing fault-tolerance requirements to modern online applications. Instead of owning hardware data centers and computing infrastructure, companies can get the same facilities by renting them from a cloud services provider. To choose the right vendor for your enterprise needs, you should understand what is cloud computing services, and know the difference between available platforms. Learn about today's market leaders with the proven reliability and quality of service.

    The Cloud Computing Pyramid

    There are a few cloud service models. They are all typically represented as a pyramid with a different level of data control and management. The top of this pyramid is the end user that deals with personal data wrapped in a program or service with a user interface. A program/service is deployed on a specific platform that is the second pyramid level. And the basis of this pyramid is the cloud infrastructure that usually includes virtual servers, computing facilities, storage, and communication channels.

    This is what a cloud computing pyramid looks like

    There are three most common cloud computing models:

    • SaaS (Software-as-a-Service): it is the most popular cloud computing services model. The cloud provider develops and maintains programs and services, hosts them on the cloud, and offers the end-user to use them via a web browser or a desktop application. A usage, update, and customer support are available on a paid basis or for free. Samples of SaaS cloud services are file storages (Dropbox), office document processors (Google Doc, MS Office 365), photo galleries (Flickr), or messengers (Facebook).

    • PaaS (Platform-as-a-Service): it is a cloud solution where users are provided with an environment where they can perform application development, management, and delivery. Besides cloud storage and computing resources, users can get ready-made development tools, solutions for testing and maintaining their applications. IBM Bluemix, Google App Engine, Microsoft Azure, and VMWare Cloud Foundry provide their services on a PaaS model. The users of PaaS services are software developers.

    • IaaS (Infrastructure-as-a-Service): this model provides users with access to the computing resources such as servers, data storage, and networks. Web development companies and other organizations use their platforms and apps in the service provider’s infrastructure. The provider owns and manages all hardware and controls the physical and virtual infrastructure. Hetzner Cloud, Microsoft Azure, Amazon EC2, IBM Softlayer, and Giga Cloud are examples of IaaS services. The end-user of such services are companies’ system administrators.

    SaaS is the leading model due to its clarity and usability for the end-user. If you are going to develop software, you’ll need to choose PaaS or IaaS cloud services depending on your projects’ specific needs. In PaaS, you are getting particular tools like a database management system, machine learning or big data processing environments, etc. However, you don’t get access to the server OS, virtual server settings, and low-level platform settings. Renting an IaaS infrastructure, you’re getting virtual servers, network settings, and cloud storage. You also get access to the server OS and almost complete freedom in setting and deploying apps.

    Key benefits: Linux-friendly, free tier, hybrid configurations, various pricing models, extensive features.

    Possible issues: complicated setup

    Pricing: starting from $24.99/month

    Microsoft Azure was created in 2010 by Microsoft. It offers both Iaas and PaaS solutions that allow clients to run their projects purely on the cloud or combine the existing infrastructure with separate cloud services. The Azureplatform provides the ability to refuse physical servers and eliminate the on-site support team, as all technical support is cared for by Microsoft. It helps significantly cut the costs for software development and maintenance.

    While the Microsoft Azure framework is Windows, it is fully compatible with most Linux distributions. Initially offered as a PaaS, Microsoft Azure is now blurring the limits between both models, similar to many other cloud computing companies. The idea of mixing both PaaS and IaaS offers unparalleled flexibility for the end-users, now able to match various services in the way they need.

    One of the most significant advantages is a 1-year free tier plan with access to all popular services. The company also provides a decent credit to test their cloud services to ensure their suitability. Also, there are 25 “Always Free” services available for no cost. You can also pick up the specific services and configure your payment plan using their online cost calculator. If you need more add-ons or higher capacities in the future, the price will increase respectively. However, with the ‘pay as you go’ model, you will pay only for the resources you use.

    2. Google Cloud
