Free Azure Credit for Cloud Migration: How to run a Cost-safe Pilot?
Introduction
In our previous blog, we discussed application modernisation and the importance of choosing the right approach for the right workload to optimise future costs. Even if you have clearly defined the business case and chosen one of the 6R’s of application modernisation, it is prudent to run a cost-safe pilot that lets you test performance, security, availability, rollback, and the overall cost of migrating and running the application. For the pilot, select a representative but non-critical workload that lets you move from proof of concept to proof of value. One popular technique for running a cost-safe pilot is to leverage free Azure credit offerings. Before we discuss it in detail, let's first understand: What is free Azure Credit?
What is Free Azure Credit?
Free Azure credit is a prepaid cloud subsidy/handout Microsoft provides to new customers, letting them test, build, and pilot services on Azure without paying the initial amount out of pocket. This initial support reduces hesitation and lets you experiment with different combinations before building the actual applications. There are various types of free Azure credits discussed below:
Azure Free Account Credit
New users are eligible for up to $200 (USD) or the equivalent in local currency to consume on any Azure services during the first 30 days. Users also receive a free monthly amount for 20+ popular services for 12 months, and a free monthly amount for 65+ always-free services. Spending protection ensures your credit card isn't charged while you use the free Azure credit. You can cancel the offer at any time or switch to pay-as-you-go pricing to continue beyond 30 days or after the credit runs out.
Azure Credit for Startups
The Microsoft for Startups program helps founders avail start-up credits to supercharge enterprise growth and revenue. Start-ups can unlock up to $150K (USD) in credit over time by demonstrating validated progress, service adoption, and continuous Azure usage. There is a range of criteria to be eligible for the program mentioned below:
- The start-up must have a software-based product or service owned by the company
- The company should not have received more than $350,000 in lifetime free Azure credits
- Should not be a non-profit company and must be privately held
- Must not be engaged in cryptocurrency mining
- The headquarters of the company should be in a location where Azure services are available
- The startup should not be a government entity, consultancy, agency or educational institution
- The company have not raised Series C funding or later
Visual Studio Subscribers
These subscribers are eligible to receive a recurring monthly handout ranging from $50 to $150 USD to experiment with development and testing. The credit amount varies with subscription level. Visual Studio Enterprise subscribers receive $150 USD/month; MSDN Platform receives $100 USD/month, and Visual Studio Professional receive $50 USD/month.
Azure Credit for Students
The program is available only to full-time university students with no credit card requirements. Eligible students gain access to $100 USD worth of credit to be used on Azure services within 12 months. The icing on the cake is the option to renew your subscription annually and keep free access as long as you’re a student.
Now that we’ve covered the different types of Azure Free credit and the eligibility criteria, let us discuss selecting a similar but non-critical pilot workload.
Selecting a Representative but Non-critical Pilot Workload
Choosing a pilot workload is tricky. You must strike the right balance between choosing a simple application and a mission-critical one. A simple workload, such as a static website, doesn’t test landing zone capabilities, while a mission-critical workload such as ERP or a payment platform introduces vulnerability risks. To select the right pilot workload, assess its readiness against specific technical and business parameters. The ideal pilot workload must qualify these factors:
- Internal Tools: HR Applications, Employee Portals, and time-tracking systems
- Testing & Development: The workloads residing in staging environments, non-production environments or QA testing rings.
- Disaster Recovery: Implementing Azure as a secondary DR site for an on-premises application
- Reporting & Analytics: Read-only reporting databases, data warehouses, or business intelligence (BI) dashboards
Apart from the above qualifying parameters, you must also consider other factors in your decision. Avoid workloads related to revenue generation and core customer databases. On the architecture side, refrain legacy mainframes and monolithic apps with hardcoded IPs. Steer clear of workloads with heavy, multi-directional dependencies on on-premises legacy databases. Data sensitivity is a critical issue today, so also stay away from highly regulated data subject to strict compliance (PCI-DSS, HIPAA, GDPR).
Building the pilot landing zone
Once you select the pilot workload for migration and want to test its effectiveness, you must build a pilot landing zone. You can build and deploy an Azure landing zone in two ways: Platform landing zone and Application landing zone. For an Azure migration pilot, an application landing zone is preferable because it hosts a dedicated Azure environment to deploy and validate the selected workloads.
An application landing zone lets you test the entire workload journey, including application and database migration, network connectivity and access, security policies & permissions, performance & compatibility, monitoring, backup & disaster recovery, and Azure cost & resource consumption. There are also multiple application landing zone architectures, such as Azure API Management, Azure Data Factory, and Microsoft Foundry chat workload, to use.
A platform landing zone, by comparison, delivers centralised services such as centralised identity, connectivity, governance, security and management that workloads can leverage.
Testing Performance, Security, Availability, Rollback and Unit Cost
Once you have chosen the landing zone and migrated the workload, move forward to stress-test it and compare the results with the current environment. The business objective is to confirm that Azure delivers the desired performance, resilience and cost-optimization before migrating a business-critical workload. The table below shows the testing areas and validation points.
| Testing Area | Points of Validation | Success Examples |
|---|---|---|
| Performance | Response time, Throughput Speed, CPU, Memory use, disk latency, normal latency, and autoscaling under normal and peak loads | Critical transactions perform better or as well as the current environment; No resource bottlenecks |
| Security | Identity & Access Control, MFA, zero-trust architecture, least-privilege RBAC, encryption, security alert and audit logging | No glaring vulnerabilities, Unauthorized access blocked, Security events are logged and alerted |
| Availability | Component failure, service restart, backup restoration, zone or dependency failure, monitoring and automated recovery | Availability target is met; actual recovery meets the agreed RTO and RPO |
| Rollback | Ability to redirect users and data back to the original environment if migration fails | Rollback completes within the approved time, with no critical data loss or configuration gaps |
| Unit Cost | Cost per user, transaction, application instance, GB processed or business operation | Unit cost remains within the business-case target and can be forecast at production scale |
Pilot Exit Criteria: Proceed, Redesign or Stop
A successful pilot migration should deliver a clear roadmap for evidence-based decisions, not a series of fragmented results. If the performance, security, availability, rollback and unit-cost targets are met, you should proceed with the actual business-critical workload migration. However, if the pilot workload demonstrates business value but needs changes in architecture and governance, it is best to redesign the actual workload. Finally, if risks, dependencies, or costs outweigh the delivered benefits, it is advisable to stop the migration plan.
