Cloud Architecture & Network Design

Design of cloud networks and architecture — creating a scalable, secure and efficient environment that leverages cloud infrastructure, with security components designed in from the start.

The problem

What usually brings people to this.

  • Cloud environments assembled service-by-service with no overall design
  • Security controls applied after the network topology is fixed
  • Cost and performance problems traced back to early architectural choices
What we do

A scalable, secure and efficient cloud environment, designed as one system

Designing a cloud network and architecture involves creating a scalable, secure and efficient environment that leverages cloud infrastructure. We work through business requirements, cloud network type, the network design itself, the security components, native service integration and DevOps practice as a single sequence — because in cloud these decisions are not separable.

  • 01

    Cloud network design

    VPCs, gateways and internet-facing firewalls designed against the workload requirement.

  • 02

    Cloud security components

    IAM, NACLs, encryption, WAF, IPS/IDS and cloud firewalls designed into the architecture.

  • 03

    Cloud-native service integration

    Serverless architecture, containerisation and orchestration, and cloud databases.

  • 04

    DevOps practice

    Infrastructure as code, CI/CD pipelines, monitoring and logging.

Methodology

How the engagement runs.

A defined sequence, so you know what is happening at any point and what comes out of each stage.

  1. 01

    Understand business and application requirements

    Establish the constraints the architecture has to satisfy.

    • Scalability
    • Performance
    • Compliance
    • Cost efficiency
  2. 02

    Determine the type of cloud network

    Choose the deployment model per workload.

    • Public cloud
    • Private cloud
    • Hybrid cloud
  3. 03

    Design the cloud network

    Define the network fabric and its entry points.

    • VPCs
    • Gateways
    • Internet firewalls
  4. 04

    Design cloud security components

    Place the security controls inside the architecture.

    • IAM
    • NACL
    • Encryption
    • WAF
    • IPS/IDS
    • Cloud firewalls
  5. 05

    Integrate cloud-native services

    Use the platform rather than hosting the old estate on it.

    • Serverless architecture
    • Containerisation and orchestration
    • Cloud databases
  6. 06

    Establish DevOps practice

    Make the environment reproducible and observable.

    • Infrastructure as code
    • CI/CD pipelines
    • Monitoring and logging
  7. 07

    Monitoring and testing

    Validate the design under realistic conditions.

    • Simulate traffic
    • Security testing and monitoring

Technologies and frameworks in scope

  • Microsoft Azure
  • AWS
  • IAM
  • Containers
  • Serverless
  • Infrastructure as code
Typical duration Typically 15 to 30 days for assessment and one week for reporting. This varies with the size of the infrastructure.
Deliverables

What you receive.

  • 01Cloud architecture high-level design (HLD)
  • 02Cloud architecture low-level design (LLD)
  • 03Cloud security component design: IAM, RBAC, NACL, encryption, WAF, IPS/IDS and cloud firewalls
  • 04Landing zone design
  • 05Migration strategies, migration workbooks and roll-out plans
  • 06DR and BCP architecture on cloud
  • 07Testing and commissioning of cloud services
  • 08Standard operating procedures (SOPs)
  • 09Executive summary
Outcome

What changes afterwards.

  • A cloud environment designed as one system rather than assembled service by service
  • Security controls placed inside the architecture, not applied after the topology is fixed
  • No upfront hardware cost, with automated scaling and fast provisioning
  • An environment that is reproducible, observable and documented

Questions

Before you get in touch.

Is security designed in, or added afterwards?

Designed in — IAM, NACLs, encryption, WAF, IPS/IDS and cloud firewalls are part of the same sequence as the network design itself, not a separate pass applied once the topology is fixed.

Which cloud platforms do you design for?

Microsoft Azure and AWS.

Does this cover DevOps and deployment automation as well as the network?

Yes — infrastructure as code, CI/CD pipelines, and monitoring and logging are part of the same design sequence, alongside cloud-native service integration such as serverless and containerisation.

How does this relate to Cloud Migration Services?

Cloud architecture design is typically the stage before migration — the target environment is designed and validated first, then Cloud Migration Services moves workloads into it in validated stages.
