AWS v/s Azure – Understanding the key differences
Azure
Azure by Microsoft and Amazon Web Services or AWS
provides a similar set of core features and cloud capabilities. However, they
differ from each other in some essential aspects. Cloud computing refers to the
on-demand distribution of computing services over the internet and remote data
centers (i.e., the cloud) to drive faster innovation, increase resource
provisioning flexibility, and help companies gain from economies of scale.
Cloud providers like Microsoft Azure and
Amazon Web Services (AWS) have functions and services distributed across
multiple data centers. Further, cloud computing relies on two methods to enable
standardization and cost efficiency: a resource-sharing model and a
“pay-as-you-go” paradigm. In simple words, cloud computing allows users to rent
rather than buy their IT infrastructure. Customers choose to access
computational power offered by service providers like AWS and Azure over the
internet or the cloud and pay for it as they use it, rather than investing
extensively in databases, software, and hardware.
Amazon Web Services (AWS), a subsidiary of the
eCommerce and technology giant Amazon. It offers over 200 services from data
centers worldwide and has millions of users across startups, large enterprises,
and leading government agencies.
Microsoft Azure, often known as Azure, is another
top cloud computing service. It aids in the management of applications through
Microsoft-operated data centers. The platform provides many cloud services
including analytics, computing, storage, and networking. Azure, like AWS, has
an extensive toolkit that is constantly growing and has been the industry
leader in cloud computing for more than ten years.
Key Differences Between AWS and Azure
Here are the leading differences between AWS and
Azure, explained in detail.
The approach to computing power
provisioning and usage
The primary issue with computing is scalability. To
address this, AWS uses elastic cloud computing (EC2), in which the resource
footprint available may increase or shrink on-demand as a result of elastic
cloud computing resource provisioning. Local clusters provide just a piece of
the resource pool that is accessible to all processes simultaneously. EC2 users
may construct their virtual machines (VMs), pick machine images (MIs) that are pre-configured,
or modify MIs, and they can change the power, size, and memory of the VMs
required. They can also choose the number of virtual machines they need. On the
other hand, Azure users are given the option of creating a VM from a virtual
hard disc (VHD). It uses virtual scale sets to provide scalability and enable
load balancing. The main distinction is that EC2 may be customized for various
uses, whereas Azure VMs work in tandem with other cloud-deployment tools.
Cloud storage offerings
Success of cloud deployment depends on having
adequate storage. In this aspect, Azure and AWS are almost equally strong —
however, their offerings in this regard are different. AWS has services like
Amazon simple storage service (S3), elastic block store (EBS), and Glacier,
whereas Azure Storage Services offers blob storage, disk storage, and standard
archive. Using AWS S3, customers can gain from a scalable, secure, and robust
storage solution for unstructured and structured data use cases. In contrast,
Azure offers data storage in Azure Blogs, Azure Queues, Azure Disks, Azure
Tables, and Azure Files. Both offer an infinite number of permissible objects.
However, AWS has a 5 TB object size restriction, whereas Azure has a 4.75 TB
limit.
Security and data privacy
AWS performs an excellent job of selecting secure
alternatives and settings by default, ensuring enhanced privacy. Azure uses
Microsoft’s Cloud Defender service for security and data privacy – an
artificial intelligence-powered solution that protects against new and emerging
threats. However, Azure services may not be 100% secure by default, such as
virtual machine instances deployed with all ports open unless otherwise
configured.
Documentation and simplicity of use
AWS offers greater ease of use and is good for
first-time cloud platform adopters. The first is the dashboard, which is both
feature-rich and user-friendly. AWS also provides extensive documentation for
its cloud services. To host a simple EC2 instance, users can type their queries
into the AWS search box and navigate to “Documentation” for a video or written
lesson. However, adding users and access rules is more complex in AWS. Azure
keeps all the user accounts and information in one place, although its
documentation and recommendations system is less intuitive and search-friendly.
Networking and content delivery
Finding a secure and isolated network is vital for
cloud users, and network performance is a key parameter in cloud solutions.
Both AWS and Azure have their perspective on the creation of isolated networks.
Users can use the cloud to generate isolated private networks using AWS’
virtual private cloud (VPC). Application programming interfaces (API) gateways
are then used for cross-premises connectivity. During network connectivity,
elastic load balancing is used to ensure smooth operation. Within a VPC, users
have many possibilities for creating private IP ranges, route tables, network
gateways, etc. In comparison, Azure leverages a virtual network instead of a
VPC. A virtual private network (VPN) gateway provides cross-network
communication. Cloud-compatible firewall alternatives are available from both
AWS and Microsoft Azure to extend on-premise data centers into the cloud
without endangering data or business processes.
Machine learning (ML) modeling
Both AWS and Azure have machine learning studios for
machine learning (ML) model development. To work with AWS artificial
intelligence (AI) tools, one needs coding and data science skills. AWS’s
SageMaker gives total freedom and flexibility in creating ML models. To
implement an idea and take full advantage of AWS capabilities, the user needs
to be well-versed in Jupiter Notebook and have an expert level in Python,
making SageMaker ideal for developers with experience, coding knowledge, and strong
data engineering expertise. On the contrary, Azure ML Studio is primarily
focused on providing a codeless experience. Its interface features easy
drag-and-drop pieces that let users build a comprehensive ML model with little
to no programming knowledge. One doesn’t need to know Python or be an expert in
advanced data science techniques to participate. The service aims at data
analysts who prefer a simple interface and a visual presentation of elements.
Because artifacts and resources are stored in the same bucket and organized
into distinct folders, finding them in SageMaker is pretty simple. In Azure,
everything merges together. Artifacts related to the same model launch are
often placed in different locations, so it isn’t easy to find and study them.
