AWS vs Openstack

Published On: October 19, 2023

AWS and OpenStack are two of the most popular cloud services. AWS, known for its versatility, efficiently manages tasks such as Big Data, storage, and machine learning at a cost-effective rate. With its several data centers, it is used all around the world and excels in hosting. OpenStack, on the other hand, is known for its specialized cloud services in data storage, computation, and networking. 

When comparing AWS vs OpenStack, AWS is frequently chosen due to its wider selection of services and global presence, whereas OpenStack is preferred due to its specialization in a limited number of cloud operations. Enrolling in a cloud computing course will help you improve your skills and broaden your understanding of cloud computing services. 

What is AWS?

Amazon Web Services (AWS) is a cloud computing platform that is both cost-effective and adaptable. It offers a range of on-demand services, including processing power and storage, to support business growth. AWS is a cloud computing platform that provides numerous tools for diverse business purposes, enabling for the development of adaptable applications. 

It works on a pay-as-you-go basis, so you only pay for what you use. Being a part of Amazon, AWS makes large-scale computing more affordable than setting up physical server infrastructure.

What is OpenStack?

OpenStack is a free and open-source cloud computing platform used for Infrastructure as a Service (IaaS) in both public and private clouds. It manages processing, storage, and networking resources across data centers using various components. Users can control OpenStack through web-based dashboards or APIs. 

An important feature is its compatibility with open-source technologies and smooth integration with popular enterprise software. Besides standard IaaS functions, OpenStack includes components for orchestration, fault management, and service management to enhance the availability of user applications.

AWS vs OpenStack

AWS and OpenStack are well-known in cloud computing, with big user communities worldwide. In the AWS vs OpenStack comparison, AWS has a stronger market presence. However, OpenStack is progressively making its mark. Choosing between them depends on what an organization needs. Deciding which is better is complex and depends on what each organization requires. Here are some differences in the technologies of AWS and OpenStack to consider:


In simple terms, computation is running an application on a virtual server. AWS has a scalable virtual network called EC2, which smoothly integrates with Xen and EMR Hadoop for Big Data. On the other hand, OpenStack has an IaaS infrastructure that can grow horizontally. This means OpenStack can expand across servers by adding more machines to the existing resources, without necessarily increasing CPU or RAM.


An efficient cloud computing platform should allow you to link your servers to numerous virtual servers both internally and externally. AWS achieves this through its scalable DNS service called Route 53, Elastic Load Balancing (ELB), and Virtual Private Cloud (VPC), facilitating user connections to corporate servers. It assigns private IP addresses to DHCP-enabled instances and utilizes ELB to control traffic, directing it to Amazon EC2 instances.

OpenStack, on the other hand, provides Load Balancer as a Service (LBaaS) and flat networks VLAN, which support both automated and manual IP address and network allocation.


When deciding on cloud technologies, it’s important to think about storage. Cloud services usually have three main types: block storage, object storage, and file storage. AWS and OpenStack handle data storage differently. Block storage is for unstructured data, holding system files for virtual machines, supporting databases and read/write operations. 

Blocks and volumes store data, with files made up of evenly sized blocks, each having its own address. For block storage, AWS uses Elastic Block Store (EBS), and OpenStack uses Cinder. Object storage takes care of data and connects it to metadata. AWS uses Amazon S3 for object storage, while OpenStack uses Swift.


In a cloud computing platform, it’s crucial to be able to track how your resources are used, especially with a pay-as-you-go model. AWS provides CloudWatch for resource monitoring, while OpenStack has Ceilometer for the same purpose. While both AWS and OpenStack perform effectively, Ceilometer offers more control over logistics. 

Additionally, it’s important to note that CloudWatch is specifically designed for use within the AWS environment.


This concept basically involves controlling access to virtual servers and machines. There should be particular security groups ready to connect to new instances once they are launched. When compared to AWS, OpenStack’s security falls short of this need and may not provide the complete range of services required. 

When comparing AWS to OpenStack, AWS clearly prevails because it pursues a more secure approach and gives users a private way to access instances.


In conclusion, when considering OpenStack vs AWS, both platforms offer cloud computing services. Nevertheless, AWS stands out with its comprehensive support services and robust security measures specifically designed for businesses. Many organizations prefer AWS due to its more integrated and user-friendly environment, making it a top choice in the AWS vs OpenStack comparison.
