Adopting Multi-Cloud Services with Confidence

Adopting Multi-Cloud Services with Confidence

In transitioning to multi-cloud, IT organizations have the same responsibility to provide quality service and operational security yet have a much greater need to understand how to efficiently govern and manage these disparate cloud services.

In this session, we will examine some key patterns and models taken from a Cloud Adoption Framework through a multi-cloud lens. The presentation will include a mixture of high-level guidance, examples where vocabulary and terminology differ, and opinions on when to utilize cloud-agnostic vs cloud-native technologies for strategic decisions.

Attendees will leave with a better understanding of how to implement a Cloud Adoption Framework across multiple clouds and a higher level of confidence in their multi-cloud adoption plans.

  2. Poll: Multi-Cloud What is your opinion on multi-cloud? 1. Multi-Cloud

    is a good strategic idea 2. Multi-Cloud is a good tactical idea 3. Multi-Cloud is a bad idea 4. I don’t have an opinion on Multi-Cloud 2
  3. Excerpts from Multi-Cloud is the Worst Practice by @QuinnyPig •

    … the idea of building workloads that can seamlessly run across any cloud provider or your own data centers with equal ease. • Load balancers work differently on every cloud platform, so being multi- cloud means you’re running your own with nginx or HAproxy. • Companies don’t want to hire generalists who are broad across multiple providers; they bias for specialists who are good on one particular platform. • In practice, every “we’re multi-cloud” story I’ve ever seen in the wild means “we’re over 80% on our primary provider, then have a smattering of workloads on others.” Bad Idea?

  4. • From Multicloud Scenarios in Azure Documentation • Multicloud adoption

    should be contained to where it is required based on technical needs or specific business requirements. As multicloud adoption grows, so does complexity and security risks. • Possible Scenarios • Mergers and Acquisitions • Targeted Workloads • Technology Expertise • Cloud Migrations (from on-premises or another provider) • … Fact of Doing Business?

    organizations align their business and technical strategies in order to accelerate a successful cloud adoption. Cloud Adoption Framework
  9. • Organizes guidance into six areas of focus called perspectives

    • Each perspective is made up of capabilities describing “what” a stakeholder owns or manages • Each capability provides guidance related to skills and processes • Assists in developing action plans and creating work streams AWS Cloud Adoption Framework 9 Source: https://aws.amazon.com/professional-services/CAF/

  25. Thoughts Conway’s Law “Any organization that designs a system (defined

    broadly) will produce a design whose structure is a copy of the organization's communication structure.” — Melvin E. Conway • Your Organization Unit / Folder / Management Group hierarchy doesn’t need to mirror your current organizational structure. • What problems does a future re-org or M&A leave you with? • Consider a structure organized by workload 25

  27. • A tag is a label consisting of a user-defined

    key and value attached to resources as metadata • Tags help you organize your resources and can enable cost allocation, automation, and access control • Tags can be IT aligned • Workload, application, function, or environment • Tags can be Business aligned • Accounting, business ownership, or business criticality Resource Consistency - Tags 27

  29. Thoughts • Define an organizational tagging standard early • Use

    lower-kebab-case for tag keys • Define a prefix strategy for standard (platform) tags vs. project (workload) tags • Allows teams to combine organization and project standards without conflicts • Use both reactive and proactive approaches for governing tags • Leverage cloud-native tooling • Understand that cloud providers are not internally consistent • Some services still lack tags, don’t support tag-on-create, or have other limitations 29

  36. Closing Thoughts • People and skills are your limiting factor,

    and you need to focus on workloads and business outcomes • A CCoE needs to have multi-cloud visibility into the security and governance across all your workloads and their dependencies whether IaaS, PaaS, or SaaS • Find an independent, trusted partner (specialty consultant or software vendor) who focuses all their time thinking about multi-cloud 36
