海外TECH	DEV Community	S3 types of Storage	https://dev.to/this-is-learning/s3-types-of-storage-1535	S types of StorageWe store files in S but we may need different types of storage based on our needs Like some files that are infrequently accessed some that are needed once a year so paying the same charges as a normal storage does not make sense for these So based on our needs AWS has given us various types of storage based on needs There are types of storage types in AWS S S Standard for general purpose storage of frequently accessed dataS Intelligent Tiering for data with unknown or changing access patternsS Standard Infrequent Access S Standard IA for long lived but less frequently accessed dataS One Zone Infrequent Access S One Zone IA for long lived but less frequently accessed dataAmazon S Glacier S Glacier for archivesAmazon S Glacier Deep Archive S Glacier Deep Archive for long term archive and digital preservation All these storage classes varies on the availability of our objects in our S buckets for usage Let us study each one of them in detail S StandardThis is the storage type we have been using until now it is the default for our S buckets It has low latency and high availability This is used when the data has a very frequent access It has very high availability and AWS is bound by the SLA agreement on this which makes sure its always highly available It is used for dynamic websites content distribution mobile and gaming applications and big data analytics S Standard Infrequent AccessThis has percent availability Suitable for data when is accessed less but requires immediate access when needed It requires less money for storage but whenever we retrieve the objects under this class we have to pay a fee so its not good for frequent access It is mainly used for long term storage backups and as a data store for disaster recovery files S Intelligent TieringIf you don t know where to put your data in standard access or Infrequent Access We have this storage class in which S automatically stores data according to pour retrieval rates If data is frequently accessed then it is put in standard storage other wise in Infrequent Access This is the most cost optimized class if you don t want to think in which class to put your data It is the ideal storage class for data sets with unknown storage access patterns like new applications or unpredictable access patterns like data lakes S One Zone Infrequent AccessOne Zone Infrequent Access it has all the same properties of Infrequent access except all the above storage are in availability zones but this storage class is only in one AZ so is prone to disasters It is ideal for customers who want a lower cost option for infrequently accessed data but do not require the availability and resilience of S Standard or S Standard IA It s a good choice for storing secondary backup copies of on premises data or easily re creatable data You can also use it as cost effective storage for data that is replicated from another AWS Region using S Cross Region Replication It is normally used for data that you want ti copy across regions as copying it across AZ may not make sense Amazon S GlacierS glacier is a very low cost storage available on S Normally data stored here is kept for years you normally use it for data archiving You can reliably store any amount of data at costs that are competitive with or cheaper than on premises solutions It has sub classes of data retrievals available in S glacier Expedited Data retrieval in to minStandard Data retrieval in to hoursBulk Data retrieval in to hours Amazon S Deep GlacierS Glacier Deep Archive is Amazon S s lowest cost storage class and supports long term retention and digital preservation for data that may be accessed once or twice in a year It is designed for customers ーparticularly those in highly regulated industries such as the Financial Services Healthcare and Public Sectors ーthat retain data sets for years or longer to meet regulatory compliance requirements S Glacier Deep Archive can also be used for backup and disaster recovery use cases and is a cost effective and easy to manage alternative to magnetic tape systems whether they are on premises libraries or off premises services S Glacier Deep Archive complements Amazon S Glacier which is ideal for archives where data is regularly retrieved and some of the data may be needed in minutes It has sub classes of data retrievals available in S deep glacier Standard Data retrieval in hoursBulk Data retrieval in hours S

海外TECH	DEV Community	Best Practices for Cloud Disaster Recovery in Microsoft Azure	https://dev.to/iod/best-practices-for-cloud-disaster-recovery-in-microsoft-azure-2dg0	Best Practices for Cloud Disaster Recovery in Microsoft AzureIn today s cloud era the ability to bounce back after downtime can make or break your business Disaster recovery DR capabilities should therefore be a key consideration when choosing a cloud platform Leveraging the cloud as a secondary data center for DR is often the first step in cloud adoption and disaster recovery as a service DRaaS offerings from various cloud service providers underline this fact Azure packs a punch with multiple DR options for services like VMs storage databases and containers In this blog post I ll explore these options and discuss how you can develop a robust business continuity and disaster recovery BCDR strategy for your workloads hosted in Azure What to Consider When Creating Your DR Plan in AzureContrary to popular belief applications hosted in the cloud are not foolproofーfailures happen Since application downtime can be disastrous for your business you need a well defined DR strategy to be prepared to handle failures This strategy should cover the entire application stack not just the services you think are important You might need to manually trigger the DR process yourself in order to differentiate between transient failures and actual downtimes However the failover process in Azure should be automated as much as possible Configure alerts so you can stay informed about failures and take necessary actions to trigger your DR plan With Azure you can choose to deploy application components across Azure regions to protect from regional failures If applications are regional you can deploy them in availability zones physically separated zones within a region to protect from data center failures Your choice will depend on the type of resiliency you want to deliver for your application In addition to a DR strategy that protects from cateroscopic failures you should have a backup strategy for preventing unavailability due to data corruption or application configuration Your DR strategy should also clearly define the DR process which activities will be completed when the plan is triggered and who will be responsible for executing the plan However a detailed DR strategy won t really help unless you test and fine tune it regularly This is where services that offer non disruptive DR testing such as Azure s DR solution come into play Similarly executing a regular test restore of backups in a test environment will help avoid surprises during an eventuality Disaster Recovery in Azure What Are Your Options Before developing a DR strategy you should be clear about the recovery point objective RPO and recovery time objective RTO for your workloads For example if a bit of downtime is okay with you i e non prod and test environments a complete redeployment of applications is a good choice You can also choose to adopt an active passive or warm spare approach where a scaled down secondary service is ready to take over in the event of a failure It s most effective to use an active active or hot spare architecture where instances of the application are available in multiple regions in order to accept production traffic Azure offers native capabilities built into most of its services which can be leveraged to develop a well rounded DR strategy Note that it s important to start from the ground up i e covering infrastructure if applicable as well as data and application layers in order to develop a comprehensive solution Below I ll explore the DR options for common Azure services Virtual MachinesAzure Site Recovery Azure s DRaaS offering helps protect your VMs from outages by continuously replicating them to a different paired region In the event of a disaster the VMs can be failed over to the secondary region and you can enable access from there You can also fail back to the primary region once the outage is over Organizations often use Azure Site Recovery to leverage Azure as their DR site as it supports replicating VMs in VMware Hyper V or in physical machines to Azure Azure Backup is another solution you can include in the BCDR strategy for your VMs You can use this cloud based backup service to take point in time copies of data in the VMs The backup copies can then be restored to bring your application back online in the event of data loss or corruption For the highest level of availability and resiliency from failure use a multi region architecture in which both primary and secondary regions are factored into the design StorageAn Azure Storage account can be deployed as geo redundant allowing data in the storage account to be replicated to the secondary region asynchronously In case of an outage that renders the primary end point unavailable you can initiate an account failover for Azure Storage The failover process will cause the secondary endpoint to become the primary one so that applications can continue to use the storage For Azure Blob you can use snapshots to create read only point in time copies of the data Azure files can be protected through a scheduled Azure backup You can also use the snapshot feature to create point in time copies of the data similar to Azure Blob If your application is utilizing Azure Table storage use the AzCopy tool to copy the data to a different storage account in another Azure region for DR purposes DatabasesYour DR strategy for databases will depend on whether you are using IaaS or PaaS as the deployment approach For SQL Server and SAP HANA databases hosted in VMs you can use the integrated Azure Backup feature to discover and configure regular backup without deploying any additional infrastructure There are also managed databases like Azure SQL MySQL PostgreSQL and Cosmos DB delivered as PaaS services For those databases Azure offers an automated backup service that takes regular snapshot based backups of the database to a separate storage account If you need the backups to be retained for a longer period of time Azure SQL offers a long term backup retention feature that allows you to store your backup copies in a storage account for up to years ContainersAzure provides a robust ecosystem of services to support container based workloads including Azure Kubernetes Service AKS Azure Container Instances ACI Azure App ServiceAzure Container Registry ACR AKS uses VM scale sets that can protect your workloads from node failures However to protect from regional outages you should consider multi region deployments that leverage Azure Traffic Manager to route traffic to available regions It s also important to segregate the process of recovering your application and data You can leverage Azure Storage solutions like disks and file shares to create persistent volumes for applications hosted in containers then protect that data using Azure Backup ACR s geo replication feature allows you to access your container images from a secondary region should the primary endpoint go down due to a regional outage In addition you should have a well defined DevOps process for redeploying infrastructure to a different region through IAC and for redeploying applications through a CI CD process should there be a downtime due to a cloud outage Azure App ServiceFor Azure App Service multi region deployment is the best way to minimize application downtime You can also leverage the backup and restore feature of Azure App Service which automatically creates a backup of your application configuration file content and databases connected to the app In case of regional outages applications hosted in Azure App Service will be placed in DR mode In this mode you can restore your app contents to a destination app in a different Azure region With a mature DevOps practice in place you can also restore the application by redeploying the code targeting the new destination app For serverless apps like Azure Functions and microservices based deployments it s best to separate the configuration from the code in cloud scale deployments You can use Azure App Configuration to store configuration information that can be accessed during runtime This approach also helps fast track the redeployment process of applications during a disaster ConclusionThe modern cloud scale applications deployed in Azure offer multiple options for DR Be it end to end replication using Azure Site Recovery for VMs leveraging CI CD pipelines for redeployment or the more traditional backup restore approach for services like Azure apps databases and containers the best solution for you will depend on your RPO and RTO In most cases you can create an effective solution using Azure native tools and services and by integrating elements of DR into your application architecture	2021-08-04 13:36:57
