Software as a Service (SaaS): Delivers software applications over the internet. You access the software through a web browser or mobile app. Examples include Salesforce, Microsoft Office 365, and Google Workspace. Consider what Gfi offers in terms of SaaS solutions and how they can benefit your business.
2.2. Key Provider Considerations
Service Offerings: Evaluate the provider's range of services and ensure they meet your specific needs. Consider factors such as compute power, storage capacity, database options, and analytics tools.
Pricing Model: Understand the provider's pricing model and how it aligns with your budget. Compare different pricing options and factor in potential cost savings.
Security and Compliance: Ensure the provider has robust security measures in place and complies with relevant Australian regulations, such as the Privacy Act and the Australian Signals Directorate (ASD) Information Security Manual (ISM).
Service Level Agreements (SLAs): Review the provider's SLAs to understand their commitment to uptime, performance, and support.
Location and Data Sovereignty: Consider the location of the provider's data centres and ensure they comply with Australian data sovereignty requirements. Data sovereignty refers to the principle that data should be subject to the laws and governance structures of the country in which it is collected.
3. Developing a Migration Plan
A well-defined migration plan is essential for a smooth and successful transition to the cloud. The plan should outline the scope of the migration, the timeline, the resources required, and the potential risks.
3.1. Define Migration Goals
Business Objectives: Clearly define the business objectives of the cloud migration. What do you hope to achieve? Common goals include cost reduction, improved scalability, enhanced security, and increased agility.
Key Performance Indicators (KPIs): Establish KPIs to measure the success of the migration. Examples include reduced infrastructure costs, improved application performance, and increased user satisfaction.
3.2. Choose a Migration Strategy
Rehosting (Lift and Shift): Migrating applications to the cloud without making significant changes. This is the simplest and fastest approach but may not fully leverage the benefits of the cloud.
Replatforming (Lift, Tinker, and Shift): Making minor changes to applications to take advantage of cloud-native features. This approach offers a balance between speed and optimisation.
Refactoring (Re-architecting): Redesigning applications to fully leverage cloud-native architectures, such as microservices and serverless computing. This is the most complex and time-consuming approach but offers the greatest potential for optimisation.
Repurchasing (Drop and Shop): Replacing existing applications with cloud-based alternatives. This approach may be suitable for applications that are no longer meeting your needs.
Retiring: Decommissioning applications that are no longer needed. This can help reduce costs and simplify your IT environment.
3.3. Create a Detailed Timeline
Milestones: Break down the migration into smaller, manageable milestones.
Dependencies: Identify dependencies between different tasks and ensure they are properly sequenced.
Contingency Planning: Develop contingency plans to address potential delays or issues. For example, what will you do if a critical application fails to migrate successfully?
4. Data Migration Strategies
Data migration is a critical aspect of cloud migration. It involves moving your data from your on-premises environment to the cloud. A well-planned data migration strategy is essential to ensure data integrity, security, and minimal downtime.
4.1. Data Assessment and Cleansing
Data Profiling: Analyse your data to understand its structure, quality, and volume.
Data Cleansing: Identify and correct errors, inconsistencies, and duplicates in your data.
Data Transformation: Transform your data to ensure it is compatible with the cloud environment.
4.2. Data Migration Methods
Online Migration: Migrating data over the network while the source system is still running. This approach minimises downtime but can be slower and more complex.
Offline Migration: Migrating data after taking the source system offline. This approach is faster and simpler but requires more downtime. Consider using our services to help with this process.
Database Migration Service (DMS): Using a dedicated service to migrate databases to the cloud. This can simplify the migration process and reduce the risk of errors. AWS DMS and Azure Database Migration Service are popular options.
