AWS Vs. OpenStack

Cloud computing Technology came into existence nearly 15 years back. Amazon was the initiator of cloud-based services the way back in 2006. With Cloud computing technology, data is stored over the internet instead of the hard drive. It helps to get access to files, storage, servers, etc., via internet-connected devices like computers, tablets, smartphones. Cloud service providers store and process data in place different from the end user's site. It makes the organizations free from spending huge funds on purchasing, maintaining, and servicing mechanisms themselves.

AWS and OpenStack are the two established cloud service providers. AWS is a platform where one can perform primarily any process. It can be a Big Data platform, storage, ML platform processing unit, etc. It charges significantly less amount for these platforms, hence very affordable.

Introduction to AWS

Amazon is the first architect of cloud-based web services. These cloud-based solutions were introduced over a decade ago. Today efficient web services are a major requirement for the growth and success of an organization. Amazon has several deals or features for organizations. They can choose from these features according to their requisites. It is the most accepted platform among cloud services. Amazon offers its services through a network of multiple data centers or service providers. These data centers are spread all over the world. AWS’s services are computing, database-related, delivery of content and its storage, operating system, and networking methods. Clients can choose from the offered services according to their preferences. AWS Lambda functions, Amazon Kinesis Streams, Amazon SQS Queue, are the services used to collect the humongous data. The remarkable thing here is that all these data collection services are serverless. Amazon also has the features to watch over business cloud infrastructure. The powerful management tools are there to guard the data activities in the organization. AWS CloudTrail and Amazon CloudWatch are the management tools that can be used for this purpose. These can be used to track both data activities and user actions. But two of the pulling back features are charges for every needed facility and default service limits.

Introduction to OpenStack

Considering OpenStack, it is an open-source cloud computing platform. It uses collective virtual resources to take care of public and private clouds. Here Virtualisation is about abstracting resources such as storage, CPU, and RAM from the different vendor-specific procedures before the distribution. OpenStack has a constant set of application interfaces to further decrease these virtual resources’ presence a step into separate pools. These pools empower standard cloud computing tools. Administrators and users are in direct contact with these tools. The tools that contribute to the OpenStack platform are called “projects.” It allows the business to control large storage, computation, and network clusters in a data center. These data centers can be managed through a dash console or Application Interface based on OpenStack. Among its key benefits is that its users can handle the owner’s source code. They can alter it and share the code with the community. OpenStack favors all open-source technologies and goes well with all commonly used software. Thus, it is taken as a good solution for varied infrastructure.

AWS vs. OpenStack

AWS and OpenStack are both very well-known in cloud computing fields. They have a large community of customers globally. Though AWS is more prevalent in the market, OpenStack is also on the way to establishing itself. Choosing between the both depends on the organization’s requirement. It isn’t easy to decide which of them is better. To choose between them depends on the need of the organizations.

Look at some of the differences between AWS and OpenStack of the technologies:

1. Computation

The procedure means computation to use a virtual server to run an application. AWS is unique with context to its scalable virtual network EC2 that operates flawlessly with Xen and EMR, Hadoop (distributed computing technology) based Big Data tools. AWS can develop further across servers by adding the machines to the available resources without increasing the CPU or RAM. 

OpenStack has an IaaS (Infrastructure as a Service) method that is a device to proceed horizontally. Here it is necessary to mention that OpenStack does not provide any organized support.

2. Networking

In the company’s the admin decides how the peoples working for the business connect. The right user should have access to the right resources. These connections are known as networks. To create this network, the primary server is linked to other internal or external servers.

Amazon web services has a cloud domain system named Route 53. It can connect businesses to end-users. It is a very cost-effective and reliable method. This service forms a connection between user requests and instances, which is the part of AWS. These instances running in AWS maybe load balancers such as ELB (Elastic load balancing), Amazon S3 buckets, or Amazon EC2 instances. AWS itself will assign IP addresses to models which run on DHCP, ELB provides support to give incoming traffic to EC2 instances. Amazon 53 can also be used to connect users to Instances outside of AWS. 

OpenStack LBaas (load balancing as a service) balances the load in private cloud environments. OpenStack uses VLAN technology, using which multiple independent switches can be created with a single switch. Using this technology, two users connected to the same switch but different VLANs cannot see each other’s traffic. So, OpenStack can separate the traffic of two various projects despite running on the same compute host. OpenStack provides the benefit of creating IP addresses and networks automatically as well as manually.

3. Storage

Storage is the fundamental which needs to be considered while choosing between cloud technologies. Block storage, object storage, and File storage are the three basic storage types associated with cloud computing services. Apart from that, AWS and OpenStack have some differences in storing data. Block storage is for storing unstructured data. Major storage, which is Block storage systems, keeps system files of the running virtual machines, supporting databases, and random read/write operations. Blocks and Volumes are there to store data, and evenly sized blocks make up files. Every block is assigned its address. Object storage takes care of data and links it to connected metadata. For block storage operations, AWS has EBS, and OpenStack has Cinder. For object storage, AWS has Amazon S3, and OpenStack has Swift. 

4. Security

Organizations must keep their data secure. They need to authenticate the users before they access the data. Whenever an instance is created, a separate security group(s) is assigned to it. The Security measures provided by AWS are more powerful than OpenStack. With AWS data, when transferred to the cloud, it is TLS encrypted. Users can keep track of virtual networking infrastructure.


The essential function: Who will be given access to What? Identity servers are there to implement multifactor access authentication in the cloud. Its primary objective is to manage the user identity information and the user’s authentication to access services, applications, data, and other computer resources. It helps in reducing security breaches. The application used for identity in OpenStack is Keystone, and for AWS, it is IAM. The user’s identifications run all other applications. Identification of users is the first step leading to data security, and AWS is far ahead of OpenStack

6. Private cloud architecture

AWS and OpenStack are also different in the way they form the private cloud architecture. There is a difference between the ways AWS and OpenStack build the private cloud. AWS Outposts extends the public cloud services into the on-premises data centers or private clouds. Using these frameworks, the same services can be executed on the public cloud like AWS EC2 instances on the on-premises hardware. Same public cloud monitoring and management tools can be used with private clouds.

OpenStack differs as it does not rely on a public cloud platform. It helps users install their cloud services using OpenStack Components, building core infrastructure functionality for OpenStack private clouds. But to access these functionalities, Organisations have to pay high costs. So, it becomes less preferable than AWS technology.

7. Management:

Fundamentally, OpenStack is an open-source cloud computing technology. It does not provide any official support or management services from the developers. To get this facility, a third-party OpenStack specialist is needed. This drawback proved fatal in the progress of OpenStack. On the other hand, AWS Outposts comes with built-in management support. But this feature has made AWS costlier than OpenStack. With AWS, there are also some hardware compatibility restrictions.

So, we can conclude that although both AWS and OpenStack are suitable for cloud computing services, AWS comes with built-in solid support services and security for the organizations. The obvious question that popups in our mind are from which training institute we can get comprehensive knowledge about AWS. From where we can get ourselves trained to start our career as AWS professionals. Here one should go through the curriculum of AWS Training provided in 3RI Technologies.

At 3RI Technologies, AWS Online Training is provided by seasoned AWS professional to make sure that trainees will not only have theoretical knowledge of the subject, but they will also have exposure to real-time business scenarios so that when they will start the career in the AWS world, it will not be unknown territory for them.
