Connectivity
Definition
The ability of devices to connect and communicate with each other or the internet, essential for seamless data exchange and user experience.
Use Cases
- Netflix: Delivering video streams reliably to viewers worldwide with low buffering — Uses a global content delivery approach (including its Open Connect CDN) and partners with internet service providers to place caching servers close to users, improving last-mile connectivity and reducing congestion. (Improved streaming reliability and reduced buffering by serving content closer to viewers, lowering transit costs and improving customer experience.)
- Zoom: Maintaining stable real-time audio/video calls over variable home and mobile networks — Uses globally distributed data centers and network routing strategies to connect users to nearby infrastructure and adapt to changing network conditions (latency, jitter, packet loss). (More consistent call quality and fewer dropped calls by reducing latency and improving end-to-end network performance.)
- Starbucks: Connecting point-of-sale systems and mobile app services to back-end systems for ordering and payments — Relies on secure internet connectivity from stores and customers to cloud-hosted services, using encrypted connections and redundant network paths to keep transactions flowing. (More reliable digital ordering and payment processing, supporting high transaction volumes and improving customer convenience.)
Frequently Asked Questions
- What's the difference between connectivity and bandwidth?
- Connectivity means you can successfully connect and exchange data (a working path between devices or to the internet). Bandwidth is how much data can be transferred per second over that connection. You can have connectivity with low bandwidth (it works but is slow), or high bandwidth that still performs poorly if the connection is unstable.
- When should I focus on connectivity in cloud projects?
- Focus on connectivity whenever users or systems must reliably reach cloud resources: migrating apps to the cloud, connecting offices to a VPC/VNet/VCN, enabling remote work, integrating SaaS tools, supporting IoT devices, or building multi-region apps. Plan connectivity early to avoid outages, slow performance, and security gaps.
- How much does connectivity cost in the cloud?
- Costs depend on the type of connection and how much data you move. Common cost factors include data transfer/egress charges, VPN or dedicated circuit fees (from the cloud provider and/or a telecom), load balancer and NAT gateway charges, and cross-region traffic costs. The internet itself may be inexpensive to start with, while dedicated private connectivity typically costs more but can provide more predictable performance.
