3. Top Five Cloud Giants:
Cloud Service Provider Description
Amazon Web Services Amazon Elastic Compute Cloud (EC2) is a web-based service that provides resizable compute capacity in the
cloud designed to make web-scale cloud computing easier for developers. Amazon EC2’s simple web service
interface lets users obtain and configure cloud capacity with minimal friction, providing them with complete
control of computing resources. The service allows administrators to increase or decrease capacity within
minutes, and features a lockdown security model that eliminates the possibility of human error and
tampering.
Microsoft Azure Microsoft Azure Virtual Machines allow users to deploy VMs featuring up to 416 vCPUs and 12 TB of
memory. The service providers computing options for every workload on Microsoft Azure, tapping into a
diversified range of Azure virtual machines that accommodate the applications users create. Users can
govern, monitor, and back up VM environments through the service, ensuring compliance and deploying
applications to production faster. Azure also gives recommendations for VM availability, security,
performance, and cost.
Google Cloud Platform Google Cloud Compute Engine delivers scalable, configurable virtual machines that run in Google’s data
centers with access to high-performance networking infrastructure and block storage. Users can select the
right VM for their needs, including general purpose or workload optimized VMs. Compute Engine can also
integrate with other Google Cloud services such as artificial intelligence, machine learning, and data
analytics. Google Cloud allows users to ensure applications have the capacity they need to run as they scale.
Alibaba Cloud Alibaba Cloud Elastic Compute Service (ECS) is an online computing service that offers elastic virtual cloud
servers to cater cloud hosting needs. The service provides fast memory and the latest Intel CPUs to help
users power cloud applications and achieve fast results with low latency. ECS instances come with DDoS
protection to protect data and applications from DDoS and Trojan attacks. Alibaba Cloud lets users deploy
ECS instances with just a few clicks from its console and scale capacity up or down based on real-time
demands.
IBM Cloud IBM Cloud is an open and secure public cloud for businesses that leverages open source technologies to
help users drive innovation, trust, and value. The vendor supports over 1,000 enterprise clients and over
16,000 production clusters using Kubernetes, managing cloud-native resources at unparalleled scale. IBM’s
recent acquisition of Red Hat allows them to take advantage of Red Hat Open Sight, making it easier for
users to connect and migrate Red Hat OpenShift workloads to the public cloud.

Cloud Service Provider Pricing
Amazon Web Services has three different pricing models; ‘Pay as you Go’, ‘Save when you reserve’
and ‘Pay less using more’. AWS also offers a free 12-month tier.
Microsoft Azure offers a 12-month free tier which includes access to all popular services, $200
credit and over 25 ‘Always Free’ services. They include a cost calculator and a ‘Pay as you go’
service. Each plan can be tailored to specific needs.
There is a free 12-month trial, which includes $300 towards all services and products offered by
Google Cloud Platform.
Alibaba Cloud offers a free trial covering 16 products, while advertising another 20 or more as
"always free". In addition to that, the company also gives a $300 credit for trying out its services.
IBM Cloud offers a ‘Lite’ tier. This has no time limit, will not ask for credit card details and includes
256MB of Cloud Foundry Memory. After this users have the option of the ‘Pay as you Go’ Tier
where users only pay for what they use. The website has a calculator which user can use to
estimate costs.
