Understanding Cloud Repatriation

In the modern digital age, the migration of data and applications to the cloud has been a significant trend, prompted by the promise of increased efficiency, scalability, and reduced IT costs. Cloud services such as Microsoft’s Azure Cloud have become increasingly popular, offering a host of services including computing power, storage solutions, and advanced analytics. But as with any technology, the cloud has its limitations, and businesses are beginning to realize that not all applications and workloads are suited to the cloud environment. This has given rise to a new trend – cloud repatriation.

Cloud repatriation, sometimes referred to as de-clouding, is the process of moving workloads and data back from the cloud to on-premise or local data centers. While it may seem counter-intuitive in the age of digital transformation, many businesses are finding it a necessary step to maintain control over their data, reduce costs, and overcome performance issues associated with the cloud. This process of migrating back to an on-premise environment from Azure Cloud is what we refer to as Azure Cloud Repatriation.

The concept of Cloud Repatriation

Cloud repatriation is not a new phenomenon but has gained significant attention recently. The initial appeal of the cloud was undeniable, with its promise of unlimited scalability, reduced hardware costs, and access to advanced technologies. However, as businesses dived into the cloud, certain issues began to surface. Some companies found their cloud expenditures spiraling out of control, while others discovered that their specific workloads didn’t perform as well in the cloud as they did on-premise. Then there were issues related to compliance and data sovereignty.

All these factors combined, led businesses to rethink their cloud strategies and consider the option of cloud repatriation. But why are businesses considering cloud repatriation, you might ask? Well, there are several factors at play here. Cost considerations, the need for greater control, security concerns, and performance issues are some of the leading drivers for businesses to move their workloads back on-premise. However, the process of repatriation is not straightforward.

There are several challenges that businesses need to overcome. It requires careful planning, selecting which workloads to move, preparing the on-premise environment, and actually moving the data and applications. It’s not just a simple case of ‘lifting and shifting’. It involves considerable time and resources and needs to be done in a manner that minimizes business disruption.

In the next few paragraphs, we will delve into the Azure Cloud, understand its benefits and common use cases, and why businesses might want to move away from it to an on-premise environment. We will then explore the process of Azure Cloud Repatriation and how businesses can simplify it with the help of Carbon, a software tool developed by SmiKar.

A deep dive into Azure Cloud

Microsoft Azure is a comprehensive set of cloud services that organizations use to build, deploy, and manage applications through Microsoft’s global network of datacenters. Fully integrated with Microsoft’s software offerings, it provides a robust platform that enables organizations to take advantage of the flexibility and efficiency of cloud computing. This includes scalable computing power, vast storage solutions, and advanced analytics and AI services that allow businesses to transform their operations and achieve their strategic objectives.

While it’s renowned for its PaaS capabilities, Azure also excels in its IaaS offerings. It supports a wide range of programming languages, tools, and frameworks, both Microsoft-specific and third-party, offering a flexible and friendly environment for developers. Besides, it provides robust security with its Security Center, a unified infrastructure security management system that strengthens the security posture of data centers and provides advanced threat protection.

With the help of Azure, businesses have been able to scale their operations, build and deploy a variety of applications, manage data effectively, and gain insights to make data-driven decisions. Whether it’s computing power they need, a place to store massive amounts of data, or advanced analytics and AI capabilities, Azure has been the go-to cloud platform for many businesses.

Benefits of Azure Cloud

One of the most significant benefits of Azure is its seamless integration with other Microsoft products, making it an ideal choice for organizations heavily invested in Microsoft technologies.

It also offers substantial cost savings by eliminating the need to invest in and maintain on-premise hardware. With its scalability, businesses can easily scale up or down their resources based on their needs, paying only for what they use. In terms of security, Azure provides robust security measures, with security analytics and threat intelligence built into the platform. It also offers tools for regulatory compliance, making it an attractive option for businesses in regulated industries.

Lastly, Azure’s global footprint with data centers worldwide allows businesses to deploy their applications close to their customers, reducing latency, and improving user experience.

Common use cases of Azure Cloud

Azure is often used for data backup and disaster recovery due to its reliability and robustness. It’s also commonly used for building, deploying, and managing applications and services, thanks to its PaaS offerings. Additionally, businesses use Azure for data analytics and artificial intelligence, utilizing its advanced capabilities to gain insights and make data-driven decisions.

Why migrate from Azure Cloud to On-premise?

In many instances, Azure also supports the shift towards a remote work environment by providing a secure and scalable platform for virtual desktops and collaboration tools.

The need for control and security

One of the primary reasons for Azure repatriation is the need for more control over data and infrastructure. With Azure, while Microsoft takes care of the underlying infrastructure, businesses may feel they lack control over their environment. This can be a significant concern, especially for businesses in highly regulated industries or those dealing with sensitive data. On-premise environments provide businesses with complete control over their data, including where it’s stored, who can access it, and how it’s protected.

Similarly, while Azure provides robust security measures, some businesses might still prefer the security of having their data on-premise. This could be due to specific regulatory requirements or simply a preference for having physical control over their data.

Cost considerations

While cloud services offer the promise of reducing IT costs, the reality can be quite different. Depending on the usage pattern and the specific workloads, the costs of running services on Azure can quickly add up. These can include not just the costs of compute and storage, but also network costs, and the costs of other Azure services. For businesses with stable and predictable workloads, it might be more cost-effective to host these workloads on-premise, even when considering the costs of purchasing and maintaining hardware.

Performance and latency

While Azure’s global footprint allows businesses to deploy their applications close to their customers, there might still be performance issues or latency, especially for businesses serving a local or specific geographic market. In such cases, hosting the applications on-premise might provide a better user experience.

The Process of Azure Cloud Repatriation

The process of repatriating workloads from Azure Cloud to on-premise environments can be complex and requires careful planning.

Planning for Repatriation

Before initiating the repatriation process, businesses need to thoroughly evaluate their workloads and identify which ones would benefit from being on-premise. They need to consider the costs, performance requirements, and security and compliance requirements of these workloads.

Selecting VMs for Repatriation

Once the workloads have been identified, the next step is to select the Virtual Machines (VMs) on Azure that host these workloads. These VMs would need to be replicated and migrated back to the on-premise environment.

Preparing the on-premise environment

Finally, before the repatriation can begin, the on-premise environment needs to be prepared. This includes setting up the necessary hardware, configuring the network, and setting up the virtualization platform, whether it’s VMware or Hyper-V.

This process, while necessary, can be time-consuming and complex, especially for businesses with large numbers of VMs or complex applications. This is where Carbon, a software tool developed by SmiKar, can help.

Azure vs AWS – Comparing IaaS Resilience

by Mark | Aug 27, 2019 | AWS, Azure, Comparison, IAAS, Resilience

IaaS Resilience, which cloud platform is better? Azure or AWS?

Now this blog post is only going to cover the two largest cloud providers, Microsoft’s Azure and Amazon’s AWS and only focusing on Infrastructure as a Service (Azure VMs for Azure, and EC2 for AWS) offerings they both provide, but with a bit of a deep dive in to the way they both provide resilience. Also with some architecture best practices to ensure your infrastructure and furthermore your applications remains available in the event of failure so that you can still provide applications to your user base and more importantly to your end customers. When designing your cloud IaaS deployments knowing how best to architect for high availability and resilient infrastructure is required, so knowing the in’s and outs of the major cloud providers is a must.

In this first part of a multiple blog overview we will cover off both AWS and Azure’s datacentre construction.

Azure and AWS Data Centre Comparison

Let’s start to look at how they each construct their data centres and provide you with their platforms for your Infrastructure as a Service deployments.

AWS Availability Zones and Regions

AWS Datacentres

First off the bat, let’s see how AWS setup their Datacentres. AWS has 69 Availability Zones dispersed over 22 geographic regions throughout the world (as of August 2019, but we can expect this number to grow as they continue to expand.)

Amazon Web Services Regions

Each AWS region is separated by geographic location and are totally independent from one another and are also made up of multiple AWS availability zones. Wikileaks actually released the locations of each AWS datacentre (some are AWS owned others are co-located datacentres). This isolation between regions is provided by completely separate infrastructure, that includes cooling, power and water supply. Every AWS region will have a minimum of two availability zones and each Availability Zone will have a minimum of one datacentres within each AZ, with connectivity between each datacentre within the AWS region having redundant low latency network connections between them.

What is an AWS Region?

In the picture above I have focused on the Sydney Australia AWS Region, which is comprised of three availability zones, multiple data centres (thanks to our wikileaks friends we know there are 8 in the Sydney region) and each with high bandwidth, low latency private redundant fibre connections which allows synchronous replication of services between each AZ.

So what is an AWS Availability Zone?

So what is an Availability Zone? Well by AWS own definition an ‘Availability Zones are the core of our infrastructure architecture and they form the foundation of AWS’s and customers’ reliability and operations. Availability Zones are designed for physical redundancy and provide resilience, enabling uninterrupted performance, even in the event of power outages, Internet downtime, floods, and other natural disasters.’ As stated before each AZ is made up of one or more datacentres but are logically grouped as one datacentre (availability zone) for all intents and purposes.

Having numerous Regions with multiple availability zones all with isolation and fast reliable network connectivity between them provides you with great fault tolerance and stability for your EC2 instances.

Azure and AWS Resilience Comparison

Feature	AWS	Azure
Regions	25 regions as of 2021 with plans to expand	60 regions as of 2021 with plans to expand
Availability Zones	82 Availability Zones as of 2021	62 Azure regions have 160+ data centers in more than 60 regions
Service Level Agreement (SLA)	Offers SLAs for most services, with a 99.99% uptime guarantee for some services	Offers SLAs for most services, with a 99.99% uptime guarantee for some services
Disaster Recovery	Offers disaster recovery solutions for various scenarios such as site failure, regional disasters, and data loss	Offers disaster recovery solutions for various scenarios such as site failure, regional disasters, and data loss

Load Balancing	Offers load balancing services to distribute traffic across instances	Offers load balancing services to distribute traffic across instances
Auto Scaling	Provides auto scaling to automatically adjust resources based on demand	Provides auto scaling to automatically adjust resources based on demand

It’s worth noting that both AWS and Azure have robust resilience and uptime features, with both offering SLAs and disaster recovery solutions for various scenarios. AWS has more regions and availability zones, while Azure has a larger number of data centers overall. Both providers also offer automatic failover, backup and restore solutions, load balancing, and auto scaling features.

Azure Regions and Availability Zones

Cloud Regions

Up until recently Availability Zones were not available within Microsoft Azure, but they have recently just come to the party (Availability Zones are currently not available in Australia, but we have four Azure Regions. The first Australian Region to offer Azure Availability Zones will be Sydney with commissioning of this AZ slated for some time in 2020). Previously Microsoft thought multiple regions was better for their cloud environments over the AWS AZ model, but there are limitations with just using regions.

The biggest issue with a region only approach is that the network between each region and the large distance between them would only allow asynchronous replication. This translates to data discrepancies as it was impossible to achieve a recovery point objective of zero which means possible data loss should an Azure region have an outage and you need to fail over your application and services. Now dependent on what business you are in this loss of data maybe not such a big problem, but if for example you are a bank, where a loss of 1 millisecond of data could contain millions of dollars of lost transactions that would be a huge problem. Luckily for us, Microsoft is rapidly building more datacentres and availability zones

Microsoft Azure Regions

Microsoft has currently at the time of writing this article 54 Azure regions available worldwide and is available in 140 countries. An Azure region is very similar to an AWS region, being that they are sets of datacentres that are connected with a low latency network between them. Microsoft do have selected Region pairs, depending on the storage replication you choose, your data will be asynchronously replicated to the closest available region. (For example, if your main Azure Region is Melbourne, your data can be replicated to the Sydney Region).

Microsoft Azure Availability Zones

Microsoft’s Azure Availability Zones are being rolled out over the next few years, so we can expect them to have the same resiliency as AWS for your cloud Azure VM deployments. The Azure AZs are unique physical locations and have independent power, cooling and networking from each other, with the physical separation providing you with protection from datacentre failure. Azure Regions and Availability Zones will provide you with a reliable, resilient and expanding platform for you to utilise for your cloud virtual machines.

So what are the differences between Azure and AWS?

Just focusing on what is discussed above, we can surmise the following;

Microsoft Azure currently has 54 regions versus AWS’s 22. Depending where your user or client base is, and to ensure quick response times of your infrastructure, Microsoft’s Azure maybe the only choice.
Microsoft have more regions closer to one another than AWS. (In Australia for example, we have four Azure Regions (but not Availability Zones as yet) compared to AWS only having the one). If for example AWS had a major outage that caused an issue to effect their whole Sydney Region, then you could possibly failover to Singapore, but expect lower performance due to the increased distance and latency (could be a problem if you have data sovereignty and need to keep your data within the Australian boundary) compared to Microsoft having four possible regions to utilise should a region have major failure. (should be noted here that two of the Australia Regions (Central 1 and 2) are only approved for use by Defense, Government and Banking, if your business does not fall under this category then you will only be able to use either Melbourne or Sydney)
AWS has more availability zones per region currently than Microsoft does, but Microsoft plan to roll out the Availability Zones as quickly as they can, so expect them to eventually have the same construct as AWS. Of course they have more regions so eventually they will over take AWS in this number.

All this alludes to two very competitive cloud vendors both trying to convince you to use their services, we really are spoilt for choice.

Azure and AWS Regions Comparison

Feature	AWS	Azure
Availability Zones	69 zones in 22 regions	Availability zones currently being rolled out
Regions	22 regions	54 regions
Virtual Machines (VMs)	Elastic Compute Cloud (EC2)	Azure Virtual Machines
