The Top 4 Business Considerations and How to Technically Implement Network Planning on Azure
If you’re looking to plan your IaaS network in the cloud, and you’re creating a business case – one of the most essential items on your to-do list should be aligning the network design with your organization’s roadmap. Usually, different requirements may arise within the organization by different verticals (security/ operation for example), and sometimes those requirements may conflict. Network planning on azure with a long-term view may reduce some of these future issues and will allow your uninterrupted operations to continue.
Additionally, without showing that your network planning meets the overarching aims of the company, you’re far less likely to get executive buy-in for your project.
Ready to start? Here’s how you can take a business requirement and use technical expertise to align it with your network planning.
Connectivity: When you think about connectivity, you need to drill down into what your resources will be communicating with. This could be a hybrid connection with your on-prem network, or a multi-cloud topology with private and/or public clouds outside of Azure. Here is also where the practice of using the Hub and Spoke topology comes into a place and where you’ll think about your internet connectivity, what will be exposed to the internet, and how you will protect your network.
Availability: Is there a business goal to ensure business continuity and high availability? This could dictate the number of instances you may use for delivering your service, the Availability Zones and Regions that you leverage, and how you want to spread your resources over VNets in Azure to ensure best-in-class availability with low latency and high speed.
Security: Using a VNet allows you to gain more security and greater control over the environment compared to using a PaaS. Network planning can involve the use of subnets which allows segregated spaces for multiple clients or services on a single network. You can use Network Security Groups to define specific communication rules between VMs and subnets. You may also wish to use more enhanced tools like next-gen firewalls, WAFs, DDoS protection, or intrusion detection and prevention solutions as guard mechanisms.
Cost: Cloud cost optimization is not a “bad word”. You want to create a network plan for your organization that stays on top of all the organization’s needs while still having a clear view of how much your monthly cloud spend will be, without any surprises. Customers often get “invoice shock” when they realize the extra charges of multi-region, cross-AZ and egress network traffic and the extra cost of such security tools additions. All of which should be included in your projections from day one.
