VM1407 Configure and Administer vRealize Business Standards and Application Services. The Microsoft Azure cloud offers a lot of services for almost every scenario that you might need. You can categorize these services into cloud computing types like. Azure App Service is considered an excellent Platform as a Service PaaS, offering an application platform for developers to build Web, mobile and API applications.

In an ideal world, all our cloud applications would be designed from the ground up to work with the cloud, they would be designed to work with cloud principals, make use of Paa. S services and provide high availability. Unfortunately, this is often not the case. We are regularly tasked with moving existing on premises applications into the cloud as a lift and shift type operation, until they can be redesigned to be cloud native. In these sort of applications, it is not uncommon for there to be a need for a shared file store. This can be a challenge in a cloud environment and was a topic I recently discussed at the Azure Saturday event in Munich slides here. The problem. Providing a shared file store an Azure has some inherent issues, particularly when looking to provide a fault tolerant solution to meet the SLA requirements. The most significant issue is one that is down to the design of the Azure platform, and that is the lack of shared storage. In an on premises world using SAN storage we can easily present the same storage to multiple machines and use tools like fail over clustering to provide a highly available file share. Download Dsl Speed Full Crack Pc. In Azure, we cannot allocate storage to more than 1 machine at a time, which means we need to look at other avenues for our shared files. Options. The challenge providing a reliable, available, file share without the use of shared storage. There are a few different ways this can be achieved, and unfortunately none of these solutions are perfect, each have drawbacks. The best solution will be the one that fits your needs with least downsides. In this article, we will consider the following Azure Files. Learn about highperformance Premium Storage and managed disks for Azure VMs. Azure DSseries, DSv2series, GSseries, and Fsseries VMs support Premium Storage. In an ideal world, all our cloud applications would be designed from the ground up to work with the cloud, they would be designed to work with cloud principals, make. Single File Server. Storage Spaces Direct. Storage Replica. DFRSThird Party Solutions. We will mainly be looking at benefits and issues with each of these solutions, rather than deep diving into the technologies and how to set them up. I do plan on producing some more deep dive articles into some of this in the future. These 6 options are ones I have picked out as being the most useful and compatible with services run in Azure. I am sure they are not the only options. I have also focused on services provided using Windows that run total in Azure, there are other services on the Linux platform, and hybrid solutions like Storsimple that we are not considering here. Azure Files. Azure files is Microsofts platform as a service Paa. S offering for providing SMB shares. Based on top of Azure storage, shares can be defined and accessed over UNC path or using the REST API. At first glance, Azure files seems like the simplest and quickest solution to the file share problem, as it provides High Availability. Redundancy and Replication including geographicallyEncryption. SMB 2. 1 and 3. Low cost. These features are enabled out of the box simply by creating a file share. However, there are some significant issues with the platform that for some will make this a no go. Security for many this is going to be the biggest issue. Access to the file share is using the storage account key, the top level security key to access the storage account. It is not possible to use NTFS permissions, or even a Sa. S key. That means if you need users to directly access the share or map drives, you are going to be giving them the storage key in plain text. This can cause all sorts of issues if people inadvertently share they key, or leave and take it with them. Access Azure file shares can be accessed externally to Azure, again using the UNC path and storage key. For some this will be a benefit, for others it is not something that would be allowed, and there is no way to turn it off. Performance Throughput om Azure files is limited at 6. MBs per the documentation, I have achieved slightly higherSize Azure file shares are limited to 5. TB total and 1. TB for a single file. Backup The Azure platform doesnt provide an easy way to backup Azure storage, and this is true for File shares. Data is replicated to deal with hardware failure, but dealing with accidental changesdeletion isnt something the platform provides. There are 3rd part tools that can assist with this, but with extra cost and complexity. Further Reading Azure Files. Single File Server. Sometimes, the simplest approach can be the best. For certain workloads, just running a single file Iaa. S file server may suffice SLA Assuming your using premium storage, single instance VMs now get a 9. SLA, not quite as good as 9. VMs, but for some applications this may be enough. Performance Having a single server of the right size and storage type can provide very good performance, especially as there is no overhead for replication or synchronisation. Backup tools like Azure Backup and Site Recovery work well with this simple setup and provide easy ways to backup data or replicate to another region. Cost A single file server has very low cost, with no additional storage costs for data replication. This solution wont work for everyone. The biggest issue is the single point of failure in the VM, even with the 9. SLA. There will still be a need to undertake maintenance on the VM, and when this occurs it will result in downtime. Your also very reliant on backup as your solution for dealing with any sort of DR event. Further Reading Single Instance SLAStorage Spaces Direct. Storage Spaces Direct S2. D is a new offering in Windows Server 2. Date is replicated across servers using a similar process to RAID, with Mirror or Parity options available. Well look at S2. D in more detail in a future post, but if you want to read more about this now you can look here. At first glance, S2. D seems to provide a nearly perfect solution to storing files in Azure It provides a true, ActiveActive cluster with instant failover in the event of a server going down. It is highly available and using Azure availability sets can survive planned maintenance events with zero downtime. It meets the Azure two machine SLA to achieve 9. It can use Azure storage as a witness rather than requiring additional VMs for this role. However, nothing is perfect and this holds true here S2. D has been designed for, and tested against, using larger files held open for long periods. Things like SQL databases, VHD files etc. It has not been tested for use as a regular file server holding lots of smaller files that are opened and closed regularly. From personal experience, whilst a lot of files function fine, I have seen some performance degradation with certain file types, such as MS Access. Because we are replicating data across multiple servers, the amount of storage is going to be double or triple that which you actually want to provision, this increases costs. There are limitations in what can be done with backup, due to the fact that S2. D uses REFS as the file system. Azure backup and ASR do not support it currently. Obviously, this requires server 2. S2. D is a good way to get a true cluster up and running in Azure, if you are either using the types of files it is intended for, or if you are willing to use it with untested file types and test the performance yourself. Further Reading Storage Spaces Direct, S2. D ARM Template. Storage Replica. Storage Replica is another new offering in Server 2. This is not a true cluster like S2. D, but instead a way to replicate data between nodes, primarily for DR purposes. Storage replica is similar to DFSR but has a few key advantages Replication is done at the block level, unlike DFSR.
