The Case for Change in Banking

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”

sendachi.com

Challenges in Banking

• Disruption: Need to Innovate

• Complicated Legacy

• Regulatory Changes

Banking: Disruption

Complicated Legacy

• Legacy Apps often using older architecture

• Complex interdependencies

• Every technology under the sun

• Thousands of servers

• A need for modernisation

• Containerisation can hasten adoption

sendachi.com

Regulatory Requirements

• Tedious auditability requirements

• Manual records

The Case for Containers

sendachi.com

Containerisation Benefits (1/2)

• Container abstraction layer

• Platform Portability

• Resilience with Clustering

• Provenance and Traceability

sendachi.com

Containerisation Benefits (2/2)

• Environment Consistency

• Improved Compute Density

• Multi-Tenancy

• Remove the Virtualisation Tax

sendachi.com

Container Abstraction Layer

• Common point of entry for containers

• Run diverse technology stacks

• HTTP with RESTful Interfaces work well

• Microservices

• 12 Factor Applications

sendachi.com

Platform Portability

• Move applications easily between servers

• Private and public cloud

• Everything is contained

sendachi.com

Resilience with Clustering

• Higher-order clustering options

• Built specifically for Docker

• Docker Swarm itself is a containerised application

sendachi.com

Provenance and Traceability

• Container builds can be automated

• Cryptographic signing available

• Docker registry comms are encrypted

• Proof that the image is as-built

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

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

sendachi.com

Multi-Tenancy

• Docker containers are insulated from each other

• Containers can’t interfere or interact with each other

• Enables greater density

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?
