Regarding cloud computing, we must confront the most contentious issue in this space — the AWS vs OpenStack argument. After all, both AWS and OpenStack are extensively utilized cloud computing technologies. At the same time, Amazon Web Services (AWS) is often selected by customers due to its superior cloud hosting capabilities and massive Data Centers. On the other hand, OpenStack is recognized for its own cloud-based shared data storage, computation, and networking services.

Comparing these two cloud systems will help us understand the distinctions between AWS and OpenStack.

What exactly is AWS?

AWS is a cloud computing platform in demand that provides various abstract technological infrastructures, distributed computing frameworks, and tools for enterprise use. Amazon Web Services offers two types of cloud computing services: service infrastructure (IaaS) and service platform (PaaS) (Platform as a Service). AWS facilitates the construction of flexible and scalable commercial applications. AWS has the advantage of being a paid-by-go service, meaning you pay only for what you use. As the name indicates, AWS is a division of Amazon. With AWS, you can take advantage of large-scale computing more economically and effectively than you could with a physical server farm.

What exactly is OpenStack?

OpenStack is accessible open-source cloud infrastructure as a cloud services platform. It consists of many components working together to manage and run huge multi-vendor hardware stacks for computing and storing networking resources throughout a data centre. Users may administer OpenStack via Web-based dashboards or RESTful APIs. The fundamental benefit of OpenStack is that it works with all open-source technology and has smooth interactions with key business software solutions.

Apart from typical IaaS capabilities, OpenStack offers orchestration, fault management, and service management, which help increase user applications’ availability.

AWS vs OpenStack

Both Amazon Web Services (AWS) and OpenStack are cloud computing behemoths with a massive global customer base. OpenStack is quickly catching up to AWS, even though AWS is more extensively utilized. The answer to the question “what’s better?” depends mainly on your company’s requirements. Consider some of the essential elements of AWS and OpenStack to make an informed conclusion.

  • Power of the computing

The calculation is a broad term that refers to executing a program on a virtual server. While AWS has its unique scalable virtual EC2 network, which operates perfectly with Xen and EMR, OpenStack offers an IaaS infrastructure with a horizontal scale. It means that OpenStack can extend over servers simply by adding machines into the existing resource pool — CPU or RAM do not need to be increased.

  • Storages

Each cloud computing platform has two kinds of storage devices, block storage and storage objects. While block storage assigns value to virtual servers for increased capacity and virtual servers backup, object storage includes media files, pictures, etc. For example, AWS has S3 in block storage, with OpenStack having Swift, whereas AWS has Cinder in object storage, and OpenStack has EBS in block storage.

  • The networking process

A decent computing cloud platform must enable your servers to be connected to other virtual (internal and external) servers. For example, AWS gives customers a connection to company computers and enhances the facility via DNS route 53, Amazon ELB, and Amazon VPC (Virtual Private Cloud). It assigns private IP addresses to DHCP and ELB cases to distribute incoming traffic to Amazon EC2 cases. BaaS and flat VLAN networks provide automatic and manual IP networks and addresses.

  • Monitoring

You might wish to know how your resources are utilized when it comes to cloud computing services. Monitoring allows you to do this for each user and to charge them according to their use. OpenStack has a ceilometer, and AWS has its Cloudwatch providers.

Whether OpenStack or AWS, they work in the same way, except that you have more control over ceilometer logistics. The AWS Cloudwatch is designed to meet AWS requirements. These services can be used for logging metrics and collecting log files, which can even be used for actions when a pre-defined threshold is satisfied. 

  • Security

AWS is leading the front about security as it offers a safer, more private manner to access user-locked instances. You can always determine who is using AWS to access your networks and instances.

  • Identity

Keystone for OpenStack and IAM for AWS determine identity functions. Identity servers enable you to access your cloud with multi-factor authentication. It may also be included by some external vendors, such as AD or LAPD.

These are the key OpenStack and AWS services. All other services operate within the scope of these applications and services.


This brings us to the conclusion of the AWS vs OpenStack discussion. While OpenStack does not have some of the preinstalled applications and installations in AWS, it may be far more customized than AWS. Moreover, OpenStack is open-source, a significant advantage. Finally, AWS promises excellent customer service, but OpenStack is more robust. In the end, everything depends on the requirement for computing and integration for your firm.
