As an Advanced Tier AWS Partner, 56Bit frequently helps businesses navigate cloud migrations, especially those moving workloads from Microsoft Azure to Amazon Web Services (AWS). While both platforms provide powerful cloud capabilities, migrating between them presents unique challenges. Stefan Caruana, who heads service delivery at 56Bit, shares insights on the top three challenges clients face during this transition and how the 56Bit team addresses them.
Q1: What are the main challenges companies face when migrating from Azure to AWS?
Stefan Caruana: “From our extensive experience, the top three challenges are:
- Differences in Cloud Architecture and Services: Azure and AWS have different service offerings, APIs, and architecture patterns. Many Azure services have no direct AWS equivalents or use entirely different configurations. This requires careful planning to avoid application downtime and data loss.
- Data Migration and Compatibility: Moving large volumes of data safely and efficiently, particularly databases and storage, can be complex. Data structures, storage formats, and security mechanisms differ between clouds, so ensuring data integrity is key.
- Security and Compliance Adjustments: Azure and AWS implement security and compliance controls differently. Companies must reassess identity management, encryption methods, and regulatory compliance standards in AWS to maintain their security posture.”
Q2: How does 56Bit approach the architectural differences between Azure and AWS?
Stefan Caruana: “We start every migration with a comprehensive cloud architecture assessment. Our certified AWS architects review the existing Azure environment, mapping workloads and identifying service dependencies.
Our approach includes:
- Re-Architecting for Cloud-Native Patterns: Instead of a simple lift-and-shift, we redesign applications to leverage AWS services like EC2, Lambda, RDS, and IAM for improved performance and scalability.
- Service Matching and Custom Solutions: When a direct Azure-to-AWS service replacement doesn’t exist, we build custom automation or use third-party tools to bridge functionality gaps.
- Proof of Concept (PoC) Deployments: Early PoC environments help validate architectural changes and identify issues before full migration.”
By investing time in this discovery phase, we reduce surprises during migration and deliver more efficient, resilient AWS deployments.
Q3: What strategies does 56Bit use to handle data migration challenges?
Stefan Caruana: “Effective data migration is crucial. Our data migration strategy focuses on minimising downtime and ensuring data integrity throughout.
Key practices include:
- Assessment and Classification: We evaluate the types and volumes of data involved, structured databases, unstructured storage, backups, and classify based on sensitivity and criticality.
- Hybrid Migration Tools: We leverage AWS Data Migration Service (DMS) alongside Azure’s data export tools for secure, incremental data replication. This approach avoids long downtime windows.
- Testing and Validation: Data consistency checks, checksum validation, and rollback plans are embedded into the migration process to prevent loss or corruption.
- Security during Transfer: All data transfers use encryption and comply with relevant regulations such as GDPR to protect sensitive data.”
This meticulous approach ensures our clients’ business continuity while their data fully transitions to AWS.
Q4: How do security and compliance frameworks change when moving to AWS, and how does 56Bit help clients adapt?
Stefan Caruana: “Security is non-negotiable, so we treat it as a priority from day one. While Azure and AWS both have robust security controls, the implementation details and tools differ significantly.
Our process includes:
- Security Posture Assessment: We audit the client’s current identity and access management, firewall rules, data encryption, and compliance controls in Azure.
- AWS Security Mapping: We map these controls to AWS services like AWS IAM, KMS (Key Management Service), Security Hub, and GuardDuty. This ensures the same or enhanced levels of protection.
- Policy and Automation: Using Infrastructure as Code (IaC) frameworks like AWS CloudFormation or Terraform, we automate security policies to enforce consistency at scale.
- Ongoing Monitoring and Incident Response: We implement AWS-native monitoring tools that integrate with existing SIEMs (Security Information and Event Management) to deliver real-time alerts and ensure rapid threat detection.
By proactively addressing security differences, 56Bit helps clients maintain compliance with industry regulations such as HIPAA, PCI-DSS, or GDPR after migration.”
Q5: What makes 56Bit uniquely positioned to support Azure to AWS migrations?
Stefan Caruana: “Our status as an AWS Advanced Tier Partner reflects our deep expertise and proven track record with AWS migrations. We combine:
- Certified AWS Architects and Engineers with hands-on experience in complex multi-cloud projects.
- A holistic approach integrating architecture redesign, data, security, and governance.
- Customised migration frameworks tailored to industry-specific regulatory environments.
- Strong collaboration with AWS professional services and access to the latest AWS tools.
Most importantly, we engage clients as partners. We provide clear communication, detailed planning, and transparent progress updates to ensure smooth, predictable migrations.”
