See webinar recording of this presentation at: https://resource.alibabacloud.com/webinar/live.htm?&webinarId=62 When first discussing a multi-cloud strategy, we must start with its importance, its reasoning (why you need it) and what formats can be adopted. Only then can we dive deeper into the different ways a customer could distribute their infrastructure across multiple clouds as well as the business and technical considerations that should be kept in mind while adopting any of these models. Finally, we will touch upon why Alibaba Cloud fits well in your Multi-cloud strategy.

Why a Multi-cloud Strategy is Essential
- 1. Why a Multi-cloud Strategy is Essential Nooruddin Abbas Ali, Alibaba Cloud
- 4. Not everything can be pushed to the public cloud All eggs in one basket? Regulations Vendor Independence Play to local strengths, globally Why Multi-cloud
- 5. Vendor Independence • Vendor specific technology • Development and Support • Product discontinuation • Rapid product change Portability Technology • Sudden price spikes Cost Cost planning & Cost optimization Business Challenge Too much dependence on a single vendor for innovation, service continuity and reliability. Eventually leading to vendor lock-in Business Challenge
- 6. Regulations • Government restrictions • Change in gov relations • Other geo-political factors Inability to work with providers from a geo graphical region Government • Compliance • DR requirements • H/A requirements Industry Inability to meet industry compliance standards Business Challenge Global Service availability with a heavy direct dependency on the the government’s global policy Business Challenge
- 7. Other Reasons to Multi-cloud Business Challenges • Service availability tied to single vendor availability • Unable to take advantage of cloud technology across the entire IT landscape • Unable to make use of the best of breed in the market All eggs in one basket? Vendor outage shutdown Not everything can be pushed to public cloud Latency Corporate policy / regulation Public Cloud provider strength Local presence Product advantages etc.
- 10. Use Case: Localization Requirement based decision-making Not restricted by 1 cloud provider’s locations No need to move everything Continue to use both cloud providers in tandem Connect the two environments if needed VPN, lease-line and other options Your business location Your existing cloud provider Your second (new) cloud provider Latency Managing multiple clouds Inter-operability
- 11. Use Case: DR Improved DR reliability Disaster Recovery not bound to a single provider Data replication across two clouds Movement out of a cloud provider for this application becomes easier in the future from both an application- and data perspective Impact of vendor-specific service issues minimized Production can be moved to the new environment in case issues are being faced with one cloud vendor Vendor Neutral infrastructure services Replication latency Managing multiple clouds Production Cloud DR Cloud replication
- 12. Use Case: Hybrid Cloud Cloud burst for peak traffic Burst private infrastructure to public cloud Distribute critical and non-critical work loads • Keep Business critical services on the private cloud • Move non-critical workloads (e.g. Test and Dev) to public cloud • Choose the environment as per application requirement • Optimize Cost Establish cloud interconnect Connect the two environments using VPN, Lease Line or via the internet. Applications must support cloud bursting Services must be interoperable Single management pane Private Cloud Public CloudInterconnect Manage from a single console (ideally) Be able to manage both environments from a single console The public cloud starts acting as an extension of the private cloud environment.
- 13. Use Case: Mixed Services DNS You can easily use a third party DNS service outside your cloud provider Content Delivery Network (CDN) It is not necessary that you use the CDN from within your cloud provider. If you find a CDN provider with better coverage in your target geography you can, in most cases, use that with your existing application. Web Application Firewall (WAF) If your cloud provider does not have WAF, or if you find better services outside, in most cases they can be clubbed with an external application Inter-provider latency and support Manual changes across two environments Too much segmentation Getting adventurous Usually replacing edge services with external ones is not a problem. If you want to get really adventurous, throw a third provider in the mix. Be weary of the challenges involved though Web Application Database Storage DNS Content Delivery Network Web Application Firewall Load Balancer Cloud provider 1 Cloud provider 2
- 14. Use Case: Distributed Workload Microservices Docker / Kubernetes Automation Ansible / Chef / Puppet API Open API support Replication Sync / Async Infrastructure Web (App) Horizontally scalabable Stateless Database Elastic Scalable Cross-vendor support Network Programmable Multiple Connectivity options Storage Object based / Globally accessible Application Multiple Architectures • Distribute one or more service layers with data / storage replication if needed • Create disparate clusters across different clouds with scheduled or continuous data synchronization • Have a single entry point to the application and build a “virtual” private cloud across multiple cloud providers
- 16. Cross-Cloud Connectivity Cross Platform Infrastructure Support Integration Tools Alibaba Cloud Alibaba Cloud in the Multi-Cloud World Sync and automation
- 17. Connectivity Options Virtual Private Network (VPN) Gateway Connect Alibaba Cloud with any other Cloud provider using standard IPSec VPN Express Connect Express Connect provides connectivity via both Dedicated Lease Line and Access Partner Network Cloud Enterprise Network (CEN) CEN allows you to create a global network to support a distributed business service with a hybrid cloud computing solution.
- 18. Infrastructure Components Operating System Most x86 enterprise operating systems are available for use in Alibaba Cloud Databases Alibaba Cloud supports industry standard databases on IaaS as well as managed services including MySQL, PostGreSQL, PPAS, MongoDB, Redis and Memcache Micro services Alibaba Cloud provides support for micro services deployment using Docker Swarm or Kubernetes. It also provides support for Container Registry services. Big Data Alibaba Cloud provides a fully managed service to deploy and manage industry standard Hadoop clusters. Supports integration with • Frameworks: Apache Spark, MapReduce, Apache Pig • Tools: Apache Sqoop, Spark SQL • Data Storage: Apache HDFS, HBase Edge Services Alibaba Cloud provides a host of edge services that can be seamlessly integrated in to a multi-cloud application architecture. Some of these services are: • DNS • CDN • WAF • Anti-DDos • OSS
