Solution property Before After Benefits
Version controlled infrastructure(using AWS CloudFormation & Sceptre1)1
● Automated deployment of MSSQL-Cluster● Mitigate future technical drift of cloud infrastructure● Reusable and consistent templates: Quick creation of
additional infrastructure / landing zones
Highly available and fault tolerant infrastructure
● Reliability, resilience and business continuity
MS SQL AG using WSFC ● Reliability, resilience and business continuity
Encryption at rest/in transit ● Security and Governance
Hybrid DNS● Delegated DNS Authority● Reliability, resilience and business continuity
16
Solution: Before and After
Solution property Before After Benefit

17
Solution: Success factors, critical phases and problems
● Carefully think about your drivers to decide on your migration strategy
● Methodology that includes change management
● Definitely start with a PoC (i.e. manual deployments)
● Once PoC works: Code / automise as much as possible
● People / culture: Developer-friendly, open communication between all parties
Success factors
18
Solution: Success factors, critical phases and problems
● Overlap between business processes (release cycles etc.) and the planning of the migration
● Resource allocation of contractors resources (in terms of timing etc.)
● Contractor resources: Conflict between functional requirements vs. non-functional requirements implementation
● Contractor resources needed to adopt their mindset to be able to work in a cloud-environment
What was critical and almost went wrong?
