Networking Basics in the Age of Cloud Networking basics stay essential, but the cloud reshapes how we design and use networks. Virtual networks, pay-as-you-go traffic, and global services mean your app can run in many places—from a single region to an edge location. This guide keeps things simple and practical, with clear definitions you can apply in teams, startups, and enterprises. It also covers common mistakes and how to avoid them. ...
Cloud Networking: Connecting Data in the Cloud Cloud networking helps data and apps talk to each other across regions, clouds, and devices. It makes services faster to reach, data transfers smoother, and security easier to manage. A clear networking plan keeps your cloud footprint scalable and reliable as new teams and workloads appear. Understanding cloud networks Every cloud provider offers virtual networks, subnets, and gateways. These elements decide where traffic goes, which services stay private, and how internet access is handled. Plan your addressing early so you can add services later without rewriting routes. Small changes in routing or naming can prevent big headaches later. ...
Cloud Security: Protecting Your Cloud from Attack Cloud security is not a one-time setup. It is a continuous effort that spans people, processes, and technology. In the cloud, security is a shared responsibility between you and your cloud provider. The provider guards the infrastructure, but you own access control, data protection, and incident response. A clear plan helps reduce risk and speeds response when threats appear. Begin with identity and access management. Enforce MFA, grant least privilege, and prefer roles over long-term keys. Rotate credentials regularly, use short-lived tokens, and review access on a schedule. Create separate admin and automation accounts, and document a secure “break-glass” procedure for emergencies. ...
Networking Basics for Cloud Architects In cloud projects, networking is the backbone that connects services, people, and partners. A clear network design helps apps scale, keeps data safer, and makes troubleshooting easier. This article covers the core ideas every cloud architect should know, from how addresses are planned to how to connect networks securely. Key building blocks These are the main parts you will use in most cloud networks: Virtual networks (VPCs or VNets) Subnets and segmentation Route tables and gateways NAT and outbound access Firewall rules and security groups Load balancers and DNS IP addressing with CIDR Private connectivity (VPN, ExpressRoute, Direct Connect) Peering and shared networks Observability: logs and metrics A simple pattern A common pattern is three tiers: public web in a front subnet, private app in a middle subnet, and a private data subnet. The web server talks to the app, and the app talks to the database. The public subnet uses an Internet gateway; the private subnets stay hidden from the Internet. Outbound connections from private subnets go through a NAT device or NAT gateway so servers can reach external services without exposing themselves. ...
