Microservices paradigm

Microservices & SOA

• Microservices inherit from SOA but the difference is the coupling

1990s and earlier 2000s 2010

Pre SOA Traditional SOA MicroservicesCoupling Decoupled

MonolithicAll Functionalities into a single process

Scaling replicating the monolith on multiple servers

MicroservicesEach element of functionality is a separate service

Scaling distributing these services across servers

Aligned DevOps strategy and implementation

Evolving OSSs to adopt micro-service architectures allows you to take advantage of the cloud and deliver on the agility promise

Agile application architectures

Improve agility, enabling quick turn-around time

Replace legacy languages and architectures with agile flexible alternatives

Tooling to aid transformation process

Elasticity & better scalability

Align with Dev Ops strategy

Improve time to market

Handle growth fluctuations more

efficiently

Hybrid choice flexibility

Legacy architectures

– Normally based on procedural languages

– Monolithic programs difficult to maintain

– Tend to be stateful so difficult to scale

– Unlikely to have a single source for business logic and data access

Modularity, Microservices for maintainability and transportability

Decomposed in Core micro services, Storage services, Messaging services

Containers for Deployment & Operational flexibility

Adoption of micro-services architecture reduces cost

from a software manufacturing and production usage perspective

• Reduced operating costs through just-in-time, on-demand capacity extension, or reduction, commensurate with business needs

• Reduced operations, administration and maintenance (OA&M) costs, Fast fault / problem detection and rapid recovery result in drastic reductions in MTTR and operations’ costs,

• Higher availability at a lower cost because of reduced redundancy in micro-service components

• Elasticity, Scalability per component or micro-service leads to lower additional virtualized infrastructure needs to address scale out situations, thus reducing the overall footprint

• Lower infrastructure costs by optimal utilization of available resources through closed loop orchestration

Adoption of micro-services architecture provides business benefits

from a software manufacturing and production usage perspective

• Enhance Competitiveness : Improvements in Time-to-Market and Time-to-Service for new or evolving network products and services

• Enabling quick turn-around time to address needed feature changes& rolling upgrades, easier and faster production deployment

• Increase revenue addressing business agility needs such as on-demand, scale out situations

• Increase Service availability, Quality of Service, with reductions in MTTR through fast fault/problem detection and rapid recovery

Example from real OSS use case with Built-in MicroService

OSS vMF – OSS Assurance non-stop in emergency situations

• Non-stop Visibility of the network

• Keep the service up and running in a transparent way for the operations teams, Built-in High Availability

• Flexibility : Balance the load of OSS Assurance micro-services to share the workload, distributed across DCs maximizing the resources usage in normal rate

• Elasticity : During Emergency, dynamically scale Out & In on demand for a certain period, with no impact on the operations and processing.

• Automation, Orchestration: Detect emergency situations (using policies), and automatically manage scale out / scale in :

• DevOps : Smoother transitions from development and test to production, accelerate deployment

TCO savings
