Words Mean Things
Summary
In our latest podcast episode, Carl and Brandon explored the fundamental aspects of cloud computing, focusing on Regions, Availability Zones, Quota, and Capacity. They discussed how regions are collections of zones, each with high-bandwidth, low-latency network connections, and the importance of deploying applications across multiple zones and regions to ensure fault tolerance and high availability. They also delved into the differences between logical and physical zones, and how regional resources can be accessed by any zone within that region. Additionally, they examined Azure’s approach to paired regions and the need for custom geo-redundant capabilities in newer regions.
The conversation then shifted to the concepts of quota and capacity in cloud computing. Quotas, synonymous with limits, ensure that each service can offer a minimum amount of resources. Carl and Brandon discussed the different types of quotas, including soft limits that can be raised through support requests, and the architectural options available when more resources are needed. They highlighted the importance of diversifying resource types to overcome quota limits and enhance application resilience. Finally, they examined capacity limitations, the concept of capacity reservations in Azure, and the differences between on-demand capacity reservations and reserved instances.
