Cloud networking and secure connectivity

Designing the private networks inside a cloud environment and the secure connections that let people, offices and systems reach them.

What it looks like

An example of the finished work

Illustrative virtual network for a fictional physiotherapy clinic. A network map shows public and private subnets with a load balancer, app servers and a database, a site-to-site VPN tunnel to the office marked Up, and remote-access users with MFA; beside it, firewall rules allow web traffic to the load balancer and database traffic only from the app subnet and deny everything else, above a log of blocked connections.

What IOPIA provides

What the work includes

  • 01

    Virtual network design

    Virtual networks and subnets laid out so public-facing services, application servers and databases are separated and only the intended paths exist between them.

  • 02

    Routing and firewall rules

    Route tables, security groups and network firewall rules that allow required traffic and deny the rest, each rule recorded with its purpose.

  • 03

    Private connectivity

    Private endpoints and internal connections so applications reach databases and cloud services without crossing the public internet where avoidable.

  • 04

    VPN connections

    Site-to-site VPNs between a cloud network and an existing office or network gateway, and remote-access VPNs for staff, configured in the cloud and on supported endpoints.

  • 05

    Identity-aware access

    Zero-trust access, where it suits, that checks who the user is and the state of their device before granting access to a specific internal application.

  • 06

    Network logging and DNS

    Private DNS within the environment, plus flow logs and alerts that show which traffic is reaching which systems.

Problems solved

When this helps

  • Databases and admin panels are reachable from the public internet because that was the quickest way to connect.
  • Remote staff share one VPN login, and nobody is sure who still has access.
  • Firewall rules have accumulated over time and nobody knows which ones can safely be removed.
  • An office or partner system needs a private connection to cloud resources, and the current setup relies on open ports.

Who it's for

  • Businesses running applications or internal systems in a public cloud that need properly segmented networks
  • Remote and hybrid teams that need controlled access to internal applications and data
  • Organizations connecting an existing office network or partner system to cloud resources

A good fit when cloud-hosted systems need private networks, clear traffic rules and secure, accountable ways for people and sites to reach them.

Public DNS, caching and protection in front of a website are covered by DNS, CDN & Edge Services. Sign-in, multi-factor authentication and account permissions across business apps belong to Identity & Access Security. Building the wider environment the network serves is Cloud Engineering & Architecture, and day-to-day device and user support is Managed IT Services.

How it works

Secure paths into a cloud network

Secure paths into a cloud networkRemote staff and an office connect through controlled access into a segmented virtual network, which separates application and data subnets and records traffic in flow logs.Remote staffsigned-in devicesOffice or sitesite-to-site VPNSecure accessVPN or zero-trustVirtual networksubnets, routes, rulesPrivate subnetsapps, databasesFlow logsmonitoring, alerts
  1. Remote staff connect through a VPN or identity-aware access that checks who they are before letting them in.
  2. An office or existing site connects through a site-to-site VPN rather than open ports.
  3. Inside the virtual network, routing and firewall rules allow only the agreed traffic between subnets.
  4. Applications and databases sit in private subnets that are not exposed directly to the internet.
  5. Flow logs and alerts record which traffic reaches which systems, so unusual activity can be reviewed.
Illustrative example — not a client system.

Scope

Included, and not included

Included

  • Review of the current network layout, rules and access paths
  • Virtual network, subnet and routing design
  • Security groups, network firewall rules and network access controls
  • Private endpoints and internal connectivity between cloud services
  • Site-to-site VPN configuration on the cloud side and supported gateways
  • Remote-access VPN or identity-aware access for staff
  • Private DNS within the cloud environment
  • Flow logging, monitoring, alerts and network documentation

Not included

  • Office network layout, Wi-Fi, switches, routers and cabling — planning for these is Network Design & Consulting
  • Public website DNS and CDN — see DNS, CDN & Edge Services
  • Compliance certification, penetration testing or a promise that a network cannot be breached
  • Internet service from the business's connectivity provider

Implementation

How implementation works

  1. Map

    Document the existing networks, rules, VPNs and who or what needs to reach each system.

  2. Design

    Agree the network layout, the traffic each path allows and how people and sites will connect.

  3. Configure

    Build networks, routing, rules and connections, defined as code where the environment supports it.

  4. Test and cut over

    Confirm that permitted traffic works and blocked traffic is refused, then switch users and sites over in planned stages.

  5. Monitor and review

    Watch flow logs and alerts, review access and rules periodically and keep the network documentation current.

Technologies

Platforms that may be involved

Platforms and approaches are selected to suit the project and the customer-specific accounts involved. Names below are examples, not partnerships or certifications. The work may involve:

  • Virtual networking on major public cloud platforms such as AWS, Microsoft Azure or Google Cloud
  • The cloud platform's managed VPN gateways and network firewall services
  • VPN protocols such as IPsec and WireGuard
  • Identity-aware and zero-trust access services, such as Cloudflare Zero Trust
  • Infrastructure-as-code tools such as Terraform for network definitions

Platform names are used to describe the work. They do not indicate a partnership or certification.

Questions

Do you set up office Wi-Fi or network equipment?
Not as part of this service, which covers cloud networks and the connections into them, configured remotely. Planning an office network — layout, Wi-Fi coverage, switches and router or firewall equipment — is Network Design & Consulting. Physical installation may be considered by special request, subject to scope, location and availability.
Do we need a VPN or zero-trust access?
It depends on what people need to reach. A VPN suits broad access to a private network or a link between sites; identity-aware access suits granting individual users access to specific internal applications. Many setups use both.
