Microsoft Azure is a powerful cloud platform that is highly suitable for enterprise IT environments with stringent compliance and data protection requirements. Over the years, it has evolved into a sophisticated cloud ecosystem. Whether you want to have a hybrid cloud infrastructure or migrate to the cloud entirely, Azure is the smart choice, and here are 5 more reasons why it’s emerging as a preferred cloud platform.

1. Streamlined Infrastructure Management with a flexible pay-as-you-go subscription model
2. Speed & Agility to deploy, test & maintain software and apps faster
3. Fully Integrated Development ensures timely upgrades and uninterrupted business continuity, creating a compelling business case.
4. Disaster Recovery with Azure Site Recovery offering robust and reliable service to ensure business continuity when hit by major faults.
5. Reduced Infrastructure Cost to get rid of reliance on maintaining local servers including installation & upgrade expenses

Want to move your apps, data & infrastructure confidently? But before you kick-start your migration to Azure cloud platform, there are a few crucial factors you need to consider.

With careful planning and meticulous execution; the on-premise to azure cloud migration could be the turning point for your business. Here are a few important factors for consideration to assess along the way:

Identify the cloud migration business objectives

It could include factors like;

• Avoiding data centers maintenance costs
• To achieve increased scalability
• Improving resiliency with better failover capabilities
• Increasing remote collaboration

Determine the budget

This would include key parameters to consider when calculating the TCO;

• Average resource unit size (could be a virtual server, storage unit and more)
• Estimated growth rate of workload
• Infrastructure overhead and management requirements (comprise of maintenance, automation, training and more)
• Average usage per month
• Security requirements

Team potential and skill gap assessment

This would require answers to the below;

• What is the team skill set level – required vs current for ensuring a smooth cloud transition?
• Does the team have prior experience with cloud migration?
• Are they equipped with the required migration tools and technologies?

Current IT infrastructure scrutiny

It would require internal brainstorming, but not restricted to just the listed points;

• Purpose of the applications (business need and future assessment)
• Volume of usage with the number of users
• Consumption level of resources (hardware, network, storage and more)
• Resource costs
• Technology framework (database servers, frameworks, software libraries, IT management tools, etc.)
• Current state of integration capabilities and limitations of the applications
• Ease of application modification
• Network, data, and application dependencies

Identify your security requirements

A detailed security assessment would reveal;

• Identity and access management
• Compliance requirements
• Disaster recovery mechanisms
• Firewalls and endpoint security

Assess your operational readiness

An essential aspect for any organization to answer post-migration;

• Ownership of operations with cloud-based applications and dependent systems
• Operational model for deployments and updates
• Consensus from involved stakeholders on the roles, responsibilities, and operational model
• Envisioning, documentation of how operations will work in the cloud
• Operational best practices benchmarking
• Business continuity or disaster recovery plan in the cloud

Assess

Start by determining the parts of your app portfolio that will benefit from migration. Evaluate apps to see if they are suitable for a cloud environment and what changes will be needed to make them perform efficiently.

Key factors to consider:

• Storage – Evaluate Azure storage services and choose a solution based on the permitted number of operations/second. Also, consider the nature of the data (hor/cold), so you know what can be stored and where.
• Networking – Explore the virtual network creation to maintain the same level of stability and performance delivered similar to the on-premise data center. Determine the number of subnets needed and define how DNS will be managed – via Active Directory or Azure DNS service.
• Scalability – Develop an understanding to dynamically scale the business apps using Azure Autoscale. Beware, this would require meticulous cost modeling.
• Virtual Machine Readiness Tool – Automated inspection of virtualized assets with a checklist help track and manage priorities of migrating them. The summary report covers the essentials of which workloads can be moved (priority & otherwise) and which ones would need further assessment.
• Microsoft assessment & planning (MAP) toolkit – The use of inventory, assessment & reporting tools helps plan migrations for the core MS stack ( including Windows Server, SQL Server, Hyper-V, Microsoft Private Cloud Fast Track) and other environments. The MAP toolkit – helps assess environments and provides readiness input for both virtual and physical workloads that are getting moved to Azure.

Migrate

During this stage, you need to choose one of the four Azure cloud migration strategies listed in the below sections. This would enable you to define the right tech stack effectively.

Key factors to consider:

• Do you want to run apps using serverless functions, in containers or use traditional VMs?
• Do you need to use hybrid cloud solutions?
• Are certain workloads compatible with the Office 365 environment but not suitable for Azure?
• Do you need to move machines with higher capacity?
• Do you have special hardware requirements which are not supported by specific VM sizes?

We recommend starting with a smaller PoC of applications that provide high value to the business and the ones that are easier to migrate. And then continue to move complex apps.

Optimize

After successful deployment, in this stage, you monitor application performance and look for ways to optimize it.

 Key factors to consider:

• Track your expenses and look for ways to optimize them with a smart mix of Azure services
• Monitor performance and make sure you’re hitting new performance milestones & meeting migration goals of at least the same performance with an on-premises model
• Plan what you can do more with Azure cloud and reinvest to further enhance capabilities

Secure & Manage

It is given that robust security and maintenance compliance help you reap the right migration benefits.

 Key factors to consider:

• Security – Get familiar with MS Azure’s security tools and recommendations to verify the security posture of the new cloud-based application. This would include checks for the functioning of security measures and respond to incidents and anomalies promptly.
• Data Protection – Azure integrates several mechanisms and services to safeguard your data. Implement all safety measures including, encryption, disaster recovery, and backup that are aligned with your compliance requirements to avoid business risks.
• Monitoring – Track the performance of data services and compute resources in real-time using tools like NewRelic or Azure Traffic Manager. This would help take the right action as all the cloud environments are dynamic and performance is not always static or even guaranteed.

For CTOs and CIOs, the choice of the right cloud migration strategy is the key to success. The migration strategy you adopt determines your choice of cloud services and the steps needed to deploy applications to them. Listed below are the four alternative strategies advised by Microsoft for migrating an application to the Azure cloud.
