Geo redundancy is to provide high availability in ________.

This article provides a baseline architecture for running web applications on Azure App Service in a single region. It details guidance for designing a secure, zone-redundant, and highly available web application on Azure. The architecture exposes a public endpoint via Azure Application Gateway with Web Application Firewall. It routes requests to Azure App Service through Private Link. The App Service application uses virtual network integration and Private Link to securely communicate to Azure PaaS services such as Azure Key Vault and Azure SQL Database. The diagram shows a virtual network with three subnets. One subnet contains Azure Application Gateway with Azure Web Application Firewall. The second subnet contains private endpoints for Azure PaaS services, while the third subnet contains a virtual interface for Azure App Service network integration. The diagram shows App Gateway communicating to Azure App Service via private endpoint. App Service shows a zonal configuration. The diagram also shows App Service using virtual network integration and private endpoints to communicate to Azure SQL Database, Azure Key Vault and Azure Storage.

In this article Azure Files always stores multiple copies of your data so that it's protected from planned and unplanned events, including transient hardware failures, network or power outages, and natural disasters. Redundancy ensures that your storage account meets its availability and durability targets even in the face of failures. When deciding which redundancy option is best for your scenario, consider the tradeoffs between lower costs and higher availability. The factors that help determine which redundancy option you should choose include: • How your data is replicated in the primary region. • Whether your data is replicated to a second region that's geographically distant to the primary region, to protect against regional disasters (geo-redundancy). Azure file shares are managed through a common Azure resource called a storage account. The storage account represents a shared pool of storage that can be used to deploy file shares. For more information about storage accounts, see When you create a storage account, you choose a redundancy setting for the storage account that's shared for all storage services exposed by that account. Therefore, all file shares deployed in the same storage account have the same redundancy setting. You might want to isolate file shares in separate storage accounts if they have different redundancy requirements. Redundancy in the primary region Data in an Azure storage account is always replicated three times in the primary region. Azure...

We are pleased to announce that the serverless Hyperscale preview now also supports zone redundancy to enable even greater high availability. Zone redundancy helps ensure business continuity in the event of a data center outage. It is simple to enable in the Azure portal or API experiences, and does not require any application changes. The only requirements are that the primary replica has at least one high availability replica and that the backup storage type is zone redundant or geo-zone redundant. The service automatically handles ensuring replicas are distributed across zones in the region. There is no additional cost for enabling zone redundancy in Hyperscale beyond the cost of the primary and HA replicas. Learn more • • •

The AWS global infrastructure is built around AWS Regions and Availability Zones. AWS Regions provide multiple physically separated and isolated Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. With Availability Zones, you can design and operate applications and databases that automatically fail over between Availability Zones without interruption. Availability Zones are more highly available, fault tolerant, and scalable than traditional single or multiple data center infrastructures. For more information about AWS Regions and Availability Zones, see AWS global infrastructure . In addition to the AWS global infrastructure, Lambda offers several features to help support your data resiliency and backup needs. • Versioning – You can use versioning in Lambda to save your function's code and configuration as you develop it. Together with aliases, you can use versioning to perform blue/green and rolling deployments. For details, see • Scaling – When your function receives a request while it's processing a previous request, Lambda launches another instance of your function to handle the increased load. Lambda automatically scales to handle 1,000 concurrent executions per Region, a • High availability – Lambda runs your function in multiple Availability Zones to ensure that it is available to process events in case of a service interruption in a single zone. If you configure your function to connect to a virtual private c...

This article written based on ourexperience on real world in messaging domain. Though the writing may not be very impressive, but we can assure you that a complete readingwill give you enough information on how to Scale with Speed. I often get requests from our clients for high availability of their Coming to redundancy, the scope is very wide. Challenges: The biggest challenge of setting up high availability application are regular updates. Any new update needs to be pushed to all the locations. If you are using a docker container, there are tools available to make your life easier. For RESTful API updates are straight forward, but in the case of large web application, it is highly recommended to use CDN for all the assets, to make the updates smoother. Now that your application is fully redundant, its time to discuss about other components such as caching Db, Database: Enough work has been done by Opensource community to make major databases highly scalable. For Humble suggestions on designing Database Architecture : One: Never limit yourself running single instance to save some cost. From day one, you must opt for a replication server sitting at different geo-location. At initial stage we try to keep application and Db on same machine to save some cost. But, what happens if you are attacked with a ransomware, when you are just getting started? Your replication server will come to your rescue. There will be some downtime, but it will save you from going into depression. ...

Contact [email protected] to schedule a meeting today! Las Vegas, United States In today’s always-on digital economy, customers are not forgiving when they experience downtime. And networking issues cause a large portion of those IT outages. According to Uptime Institute’s 2022 Data Center Resiliency Survey, networking-related problems have been the single biggest cause of all IT service downtime incidents–regardless of severity–over the past three years. Businesses incur significant costs from outages, which go beyond lost revenue. For example, the mean time to recovery (MTTR) is ramping up. According to a 2022 Opengear study, it now takes organizations an average of 11.2 hours to find and resolve a network outage, an increase of nearly two hours from a similar study in 2020. In a why geo-redundancy is essential and needs to be a business priority in the digital era. This post will focus on how to create a geo-redundant infrastructure. While networks are inherently at risk of system outages, you can take steps to mitigate that risk.

When purchasing cloud services online, you might come across numbers like 99.999% uptime or 99.9% uptime. And as far as uptime goes, “99 point anything” should seem reliable enough. After all, it’s so close to 100%, so how much can it really be lacking? And what do those extra nines mean? It’s a lot more than we think. To put it in perspective, 99.9% adds up to more than 8 hours of downtime a year, while 99.99999% adds up to only 3.15 seconds a year. Let that sink in for a minute. Depending on your business, you may need a high-availability setup with little to no downtime. To determine what that looks like, we put together a guide to high-availability infrastructure to help you understand the specific differences between three 9s, four 9s, and five 9s. Let’s dive in! Understanding the 9s: Three 9s vs Four 9s vs Five 9s Most service providers — including telecom providers — guarantee a certain percentage of uptime. This is also known as a Downtimes can occur for a few different reasons: • Electricity or internet outages • Moving devices and equipment around • Devices or equipment break down • Natural disasters • Updates and maintenance • Hacking or cyberattacks, and so on.
