For example, AWS’ General Service Commitment for Compute on EC2 instances: “AWS will use commercially reasonable efforts to make the Included Services each available for each AWS region with a Monthly Uptime Percentage of at least 99.99%, in each case during any monthly billing cycle (the “Service Commitment”). In the event any of the Included Services do not meet the Service Commitment, you will be eligible to receive a Service Credit as described below.”
What are zonal resources?
According to GCP: “Resources that live in a zone, such as virtual machine instances or zonal persistent disks, are referred to as zonal resources. Other resources, like static external IP addresses, are regional.
What are the factors to consider when choosing a zone?
Finally, when choosing which zone will be best for you, consider these four criteria to consider: 1. Latency and proximity . General rule of thumb—opt for the closest zone for lower latency. Check Stack Overflow and other forums to see what others might be saying about any zone’s latency being better than another. 2.
Where are cloud resources stored?
Cloud resources, of course, are still physical devices located somewhere on planet Earth. So even though your resources are stored in the cloud, you will still have to choose where they will be used.

Region Maps and Edge Networks
Visit here to see full list of AWS Services available in each AWS Region.
Regions
AWS has the concept of a Region, which is a physical location around the world where we cluster data centers. We call each group of logical data centers an Availability Zone. Each AWS Region consists of multiple, isolated, and physically separate AZs within a geographic area.
Availability Zones
An Availability Zone (AZ) is one or more discrete data centers with redundant power, networking, and connectivity in an AWS Region. AZs give customers the ability to operate production applications and databases that are more highly available, fault tolerant, and scalable than would be possible from a single data center.
AWS Local Zones
AWS Local Zones place compute, storage, database, and other select AWS services closer to end-users.
AWS Wavelength
AWS Wavelength enables developers to build applications that deliver single-digit millisecond latencies to mobile devices and end-users.
AWS Outposts
AWS Outposts bring native AWS services, infrastructure, and operating models to virtually any data center, co-location space, or on-premises facility. You can use the same AWS APIs, tools, and infrastructure across on-premises and the AWS cloud to deliver a truly consistent hybrid experience.
Services
AWS offers a broad set of global cloud-based products including compute, storage, database, analytics, networking, machine learning and AI, mobile, developer tools, IoT, security, enterprise applications, and much more.
What is region in AWS?
Region is a location around which they cluster multiple data centers. Latency and bandwidth within a region are usually guaranteed. Each region has multiple availability zones. AWS guarantees that the availability zones within a region are geographically separate (different data centers), while Azure has some regions that have a single availability ...
Can AWS regions connect to other regions?
When an AWS region has problems you can still connect to other regions (because they are managed through different API endpoints – FQDN/IP address), while you’re pretty much stuck if your local Azure orchestration system endpoint decides it’s time for a lunch break. Obviously I might be totally off track in which case I’d appreciate a quick correction in the comments.
Do you need connectivity between availability zones?
While the last statement is mostly true, you still need connectivity between availability zones which means that there’s still some coupling between them, and the potential for undesired spillover effects (similar to inter-AS BGP quirks ). All three providers also use a single orchestration system per region, and at least AWS already found out the hard way it’s a bad idea to run the orchestration system in a single region. Their experiment made headlines, while it seems like nobody bothers when Azure orchestration system decides to eventually deliver services.
What is GCP in networking?
Google Cloud Platform (GCP) Networking Fundamentals. If your organization or customers haven’t yet migrated to the cloud, don’t think it won’t happen, because it very likely will. If you’re a network engineer, system admin, or anyone that is supporting infrastructure in the cloud, it’s in in your best interest to understand how it differs ...
Why use Regions and Zones?
When building an application for high availability and fault tolerance, it’s crucial to distribute your resources across multiple zones and regions.
How are external IPs assigned?
External IPs are also assigned via DHCP from some Google-provided pool. These IPs are mapped to the internal IPs of the VM instances for you. You can reserve static IP addresses if needed.
What is a VPC?
VPCs are global, spanning all regions. The instances within the VPC have internal IP addresses and can communicate privately with each other across the globe. This logical representation of your network infrastructure abstracts much of the complexities of dealing with on-premises architectures.
What is a project in GCP?
Before you can do anything, you must create a project. A project is really an organizational construct used for billing and permissions. Some organizations use projects for various apps or various environments like Prod/Test/Dev; some use it for departments like Finance/HR/Marketing etc.; some use it to provide billing to customers based on their usage within a cloud-hosted environment. The important part to understand is that it’s simply a way to organize resources from a billing and permissions perspective, and each project has its own VPC network (s) isolated from other projects in GCP.
How many networks can you have in a project?
If you want complete isolation between various applications, customers, etc., you could create multiple networks. You can have up to five networks per project, including the default network. Multiple networks within a single project can provide multi-tenancy, IP overlap, or isolation within the project itself.
Can a VPC network reach a subnet?
In this diagram, you can see the default VPC network spanning multiple regions and zones, and subnets within various parts of the network servicing VMs. All of these subnets can natively route to each other, and as long as the firewalls permit it, VMs can reach one another within this VPC.
Why do Google zones exist?
Google designs zones to minimize the risk of correlated failures caused by physical infrastructure outages like power, cooling, or networking . Thus, if a zone becomes unavailable, you can transfer traffic to another zone in the same region to keep your services running.
What is a region in Google?
Region. Regions are collections of zones. Zones have high-bandwidth, low-latency network connections to other zones in the same region. In order to deploy fault-tolerant applications that have high availability, Google recommends deploying applications across multiple zones and multiple regions.
What are project wide quota limits?
Certain resources, such as static IPs, images, firewall rules, and VPC networks, have defined project-wide quota limits and per-region quota limits. When you create these resources, it counts towards your total project-wide quota or your per-region quota, if applicable. If any of the affected quota limits are exceeded, you won't be able to add more resources of the same type in that project or region.
What is a region in a compute engine?
These locations are composed of regions and zones. A region is a specific geographical location where you can host your resources. Regions have three or more zones.
What is the US West1 region?
For example, the us-west1 region denotes a region on the west coast of the United States that has three zones: us-west1-a, us-west1-b , and us-west1-c. Resources that live in a zone, such as virtual machine instances or zonal persistent disks, are referred to as zonal resources.
How to reduce network latency?
To decrease network latency, you might want to choose a region or zone that is close to your point of service. For example, if you mostly have customers on the East Coast of the US, then you might want to choose a primary region and zone that is close to that area and a backup region and zone that is also close by.
Where to find quotas in Google Cloud?
To see a comprehensive list of quotas that apply to your project, visit the Quotas page in the Google Cloud Console.
What Are Availability Regions and Zones?
Comparing Availability Zones
- Each region has availability zones, and each zone has its own data center. Each data center has its own hardware. Regions can be known for being good at some things and bad at others. For example, AWS East is known for having more downtime than AWS West. The reason for this comes down to the hardware at and usage of an availability zone. The data centers in each zon…
Global vs Regional vs Zonal Resources
- The length of the list says nothing, but the resources themselves say a lot more. Some items are standard among all zones, some resources are old and get phased out, some are new, advanced features only available in some zones. When designing your cloud infrastructure, you will want to define what tasks need to be performed where. By keeping your computation local and doing as …
Choosing An Availability Zone
- Before choosing a provider, you will need to look at where your company does business and how it does business. A few questions to consider when selecting a cloud provider are: 1. Where does your company do business? 2. Can data be stored in a single place for remote offices or must data be shared among offices across regions? 3. Will data need to get passed from one zone to …
