- 3. So what is a migration? migration noun /maɪˈɡreɪʃn/ the movement of people to a new country or area in order to find work or better living conditions Definitions from Oxford Languages These are the main points of the talk to help defining the target state and planning the migration: ●Overview of the current state, trends and scope of cloud adoption ●Values of migrating to the cloud ●Considerations on target environments ●Possible migration paths
- 4. Current state of cloud adoption Cloud consumption ●According to researchers more than 90% of organizations leverage some kind of a cloud ●55% of organizations use multiple clouds Yearly cloud spendings
- 5. Change from Planned Cloud Usage Due to COVID-19 Cloud Adoption Trends Public Cloud Adoption for Enterprises YoY
- 6. Levels of cloud usage ●Software as a Service (SaaS) User-facing: Email, IM communicators, document collaboration suites, CRMs, etc Software-facing: DBs, PubSub, Load Balancers ●Platform as a Service Environment to run and maintain workloads without the details of the infrastructure ●Infrastructure as a Service It’s still servers, networks, storage, but virtual, infinite and available instantaneously by user action or via code SaaS PaaS IaaS
- 7. Cloud and types of Cloud What is Cloud ●Cloud is a concept of infinite ephemeral resources ●Implementations ○ Public clouds ○ Private / on-prem clouds ○ Hybrid clouds: spanning across private and public
- 8. Business Drivers ●Expanding market reach: volume and geography ●Cost model: CapEx to OpEx ●Cost optimization: ownership, operations, resources ●Risk optimization ●Faster time-to-market ●Enable competitive advantage by fast experimentation ●Enhanced security
- 9. Technology Drivers At the conceptual level ●Unlimited resources ●Flexibility in technology ●Easy management of infrastructure ●Standardization/unification In conjunction with other choices ●Portability and vendor agnostic approach ●Resilience to failures: HA ●Standardization/unification ●Built-in risks mitigation: security
- 11. Public vs Private vs Hybrid Private cloud: ● More control ● Strict governance ● Comply with regulations ● More responsibility Public cloud: ● Options to choose ● Less responsibility ● Less risks ● Less control Functions Data Application Runtime OS Virtualization Servers Storage Networking Functions Data Application Runtime OS Virtualization Servers Storage Networking Functions Data Application Runtime OS Virtualization Servers Storage Networking Functions Data Application Runtime OS Virtualization Servers Storage Networking Functions Data Application Runtime OS Virtualization Servers Storage Networking Data center Platform Serverless SoftwareInfrastructure Virtual infra Virtual infra Virtual infra Virtual infra Virtual infra
