Banking and Docker Datacenter: How containers drive agility

Complex, interconnected, legacy application stacks make up modern banking platforms. The challenging environment of digital disruption is impacting the banks, software deployment cycles must speed up in response to this. This presentation explains why containerisation, specifically implemented via the Docker Datacenter toolchain is a key tool in solving this dichotomy. Learn the specific challenges and situations found within banking application delivery which the Docker Datacenter stack helps overcome and why banks need to develop a container strategy to drive successful production deployment of the Docker Datacenter and the elements of a holistic container strategy.

7. sendachi.com The Need “The digital agenda means there is an increasing need to innovate and ship even more high quality software more frequently than before into this complex technology environment”
8. sendachi.com Challenges in Banking • Disruption: Need to Innovate • Complicated Legacy • Regulatory Changes
9. sendachi.com Banking: Disruption
10. sendachi.com Banking: Disruption
11. sendachi.com Banking: Disruption
12. sendachi.com Banking: Disruption
13. sendachi.com Complicated Legacy • Legacy Apps often using older architecture • Complex interdependencies • Every technology under the sun • Thousands of servers • A need for modernisation • Containerisationcan hasten adoption
14. sendachi.com Regulatory Requirements • Tedious auditability requirements • Manual records
15. sendachi.com The Case for Containers
16. sendachi.com Containerisation Benefits (1/2) • Container abstraction layer • Platform Portability • Resilience with Clustering • Provenance and Traceability
17. sendachi.com Containerisation Benefits (2/2) • Environment Consistency • Improved Compute Density • Multi-Tenancy • Remove the Virtualisation Tax
18. sendachi.com Container Abstraction Layer • Common point of entry for containers • Run diverse technology stacks • HTTP with RESTfulInterfaces work well • Microservices • 12 Factor Applications
19. sendachi.com Platform Portability • Move applications easily between servers • Private and public cloud • Everything is contained
20. sendachi.com Resilience with Clustering • Higher-order clustering options • Built specifically for Docker • Docker Swarm itself is a containerised application
21. sendachi.com Provenance and Traceability • Container builds can be automated • Cryptographic signing available • Docker registry commsare encrypted • Proof that the image is as-built
22. sendachi.com Environment Consistency • Applications run purely inside containers • Environment information stored outside containers • The same unaltered container runs in all environments • Environmental drift is minimised
23. sendachi.com Improved Compute Density • Applications can be limited by memory and CPU • Pre-allocation of resources isn’t necessary • Intelligent scheduling of workloads with Swarm • Run larger Docker host servers without virtualisation
24. sendachi.com Multi-Tenancy • Docker containers are insulated from each other • Containers can’t interfere or interact with each other • Enables greater density
25. sendachi.com Remove the Virtualisation Tax • Docker machine can run on bare metal • Swarm orchestration optimally places containers • Swarm will replace containers on failed nodes • Any need for virtualisation?
