BizTalk 2013 Azure VM (IaaS) High availability

Hi,
We have a 2 BT , 1 SQL configuration for the BizTalk Environment. BizTalk 2013 VMs and SQL 2012 VM provisioned from the gallery. Since there is a limitation on having a highly available SQL tier (for BizTalk) on Azure, we are evaluating a possible
replacement of the Azure setup with a on-premise setup which will guarantee highly available environment(as the SQL tier will be highly available too and with the SSO service). Wanted to know your thoughts on the below topics.
1) Is the BizTalk 2013 Azure (IaaS) used widely in production scenarios today (given the limitation for HA). If yes, what could be the mitigating solution
2) Is the roadmap for Microsoft (BizTalk Server related) going to address this scenario.
Appreciate your inputs in this regard which would help us to make an informed decision to switch back to on-premise.
Thanks,
Ujjwal

Theoretically since SQL Always-ON or database mirroring is not supported with BizTalk, SQL Server Azure virtual machines do not support Failover Cluster Instances.
But ensure by selecting “Availability Set” your virtual machine will be deployed to different fault domains and update domain thus ensuring that your application is available during network failures, hardware failures, and any planned downtime. This increases
the case of server/service high availability. And with these features unavailability of the server in Azure is very less.
But if you’re one of those customers you still want to ensure they don’t let any chance of failure (or don’t afford for any failure) and still look to implement failover Cluster Instances, then simple answer is SQL Server Azure virtual machines do not support
Failover Cluster Instances. If you ask about mitigation plan, then ensure you have selected “Availability Set” while provisioning the servers.
To answer to you couple of specific questions:
1) Is the BizTalk 2013 Azure (IaaS) used widely in production scenarios today (given the limitation for HA). If yes,
what could be the mitigating solution - Ican't
answer BizTalk as Iaas is widely used, this question has to be asked to Microsoft directly. And regarding the mitigation plan, as mentioned provisional your server across fault
domains and update domain minimize the down time or increases the high availability.
2) Is the roadmap for Microsoft (BizTalk Server related) going to address this scenario. - As of now SQL Always-ON or database mirroring are not supported for BizTalk and roadmap remains same.

Is the Azure Files data highly available/replicated under the covers?

I am assuming that with Azure Files, under the covers data is replicated multiple times for High Availability. Is that correct? For some applications, typically failover application, where the application doesn't assume highly available storage;
the applications themselves build logic to either replicate/sync data. An example is Elastic Search. In these cases, the system lands up making too many copies. Is the Azure File Semantic the same as blob store, in this regard.

Choosing VM as high availability for BizTalk's SQL Server databases

Hi,
I'm lloking to choose the architecture of our BizTalk 2013 solution.
The application server will be build on virtual machines, but I still have interrogation about the SQL Server.
Is a SQL Server on a VM supported for BizTalk 2013 ?
Because in case of physical failure, the VM moved to another server can we considered the VM as a solution of High-Availability ?
thanks for your reply.

When the SQL VM fails over what attributes of the server will change? If everything including the server name, the mapped SAN locations (for Databases) and/or the versions of SQL will remain the same then it will behave like a temporary network outage between
the Front-end and the SQL.
If however, the failed over VM has a different set of mapped location for DB then you would need to establish a BizTalk Log Shipping between SQL VM 1 and SQL VM 2. In this scenario, the recovery will require time and cannot be automatic.
A word of caution though. If you have SLA's pertaining to transactions/messages per second with the customer then you might want to evaluate having dedicated boxes of SQL. The SQL Licensing is PER CORE and in a VIRTUAL ENVIRONMENT all the
CORES have to be licensed since the Virtualization does not permit you to BIND the VM to a specific set of CORES. The same would apply for your BizTalk Servers. This just might work out costlier as opposed to the dedicated server environment.
Regards.

Azure image - Biztalk 2013 R2 Enterprise

Hi
Can anybody explain why Biztalk 2013 R2 Enterprise isn't an available Azure image?
Thanks
Paul

The R2 developer edition has just been released couple of weeks. So I guess people at Microsoft are still working on getting those images sorted out.
Do you require specific features of the R2 edition? Otherwise you could go ahead with the 2013 Enterprise Image.

SharePoint Foundation 2013 - Can we use the foundation for intranet portal with high availability ( medium farm)

Today I had requirement, where we have to use the SharePoint Foundation 2013 (free version) to build an intranet portal ( basic announcement , calendar , department site , document management - only check-in check-out / Version).
Please help me regarding the license and size limitations. ( I know the feature comparison of Standard / Enterprise) I just want to know only about the installation process and license.
6 Server - 2 App / 2 Web / 2 DB cluster ( so total license 6 windows OS license , 2 SQL Server license and Guess no sharepoint licenes)

Thanks Trevor,
Is load balance service also comes in free license... So, in that case I can use SharePoint Foundation 2013 version for building a simple Intranet & DMS ( with limited functionality). And for Workflow and content management we have to write code.
Windows Network Load Balancing (the NLB feature) is included as part of Windows Server and would offer high availability for traffic bound to the SharePoint servers. WNLB can only associate with up to 4 servers.

Exchange 2010 to Exchange 2013 Migration and Architect a resilient and high availability exchange setup

Hi,
I currently have a single Exchange 2010 Server that has all the roles supporting about 500 users. I plan to upgrade to 2013 and move to a four server HA Exchange setup (a CAS array with 2 Server as CAS servers and one DAG with 2 mailbox Servers). My
goal is to plan out the transition in steps with no downtime. Email is most critical with my company.
Exchange 2010 is running SP3 on a Windows Server 2010 and a Separate Server as archive. In the new setup, rather than having a separate server for archiving, I am just going to put that on a separate partition.
Here is what I have planned so far.
1. Build out four Servers. 2 CAS and 2 Mailbox Servers. Mailbox Servers have 4 partitions each. One for OS. Second for DB. Third for Logs and Fourth for Archives.
2. Prepare AD for exchange 2013.
3. Install Exchange roles. CAS on two servers and mailbox on 2 servers. Add a DAG. Someone had suggested to me to use an odd number so 3 or 5. Is that a requirement?
4. I am using a third party load balancer for CAS array instead of NLB so I will be setting up that.
5. Do post install to ready up the new CAS. While doing this, can i use the same parameters as assigned on exchange 2010 like can i use the webmail URL for outlook anywhere, OAB etc.
6. Once this is done. I plan to move a few mailboxes as test to the new mailbox servers or DAG.
7. Testing outlook setups on new servers. inbound and outbound email tests.
once this is done, I can migrate over and point all my MX records to the new servers.
Please let me know your thoughts and what am I missing. I like to solidify a flowchart of all steps that I need to do before I start the migration.
thank you for your help in advance

Hi,
okay, you can use 4 virtual servers. But there is no need to deploy dedicated server roles (CAS + MBX). It is better to deploy multi-role Exchange servers, also virtual! You could install 2 multi-role servers and if the company growths, install another multi-role,
and so on. It's much more simpler, better and less expensive.
CAS-Array is only an Active Directory object, nothing more. The load balancer controls the sessions on which CAS the user will terminate. You can read more at
http://blogs.technet.com/b/exchange/archive/2014/03/05/load-balancing-in-exchange-2013.aspx Also there is no session affinity required.
First, build the complete Exchange 2013 architecture. High availability for your data is a DAG and for your CAS you use a load balancer.
On channel 9 there is many stuff from MEC:

SharePoint 2013 High Availability - BI Semantic

SharePoint 2013 High Availability
Hi all,
Settings
Two Sites connected via tunnel, no issue in networking – Single farm
SQL2012, two DB with mirroring
SharePoint 2013, two servers in the farm, each server is APP & WEB
Issue, this has been designed against full site failure (e.g. losing connection to other site, which means losing 1 SQL and 1 SP server)
When users try to view some reports from the BI page, they can’t , we have confirmed that SQL mirrors are failing correctly, the issue (we think to be to access the SharePoint reporting services DB which we have mirrored as well), any help will be great.
Regards

Okay, if you've validated that you have the 1Gbps and 1ms over 10 minutes average, then you're in a supported scenario. How did you configure the SSRS databases to use mirroring within SharePoint? With SSRS databases, you'll need to use PowerShell:
$database = Get-SPDatabase | where {$_.Name -eq "ReportingServiceDbName"}
$database.AddFailoverServiceInstance("InstanceName")
$database.Update()

BizTalk 2013 SFTP Adapter : Host Instance configured for SFTP Receive cause high CPU usage

Hi,
Our BizTalk 2013 Server test env have 16 GB RAM. We have one SFTP Receive Location which is using a dedicated Host instance for SFTP receive.
As soon as we start this SFTP Host Instance it starts consuming 50-60% CPU. (Even when it is not handling any file receive)
As suggested in below thread, to fix this issue, we changed the SFTP RL default configuration. i.e. Changed polling interval from default 0 sec to
10 minutes and also changed the RL Schedule window to business hours only.
https://connectedpawns.wordpress.com/2014/04/13/biztalk-2013-sftp-adapter-biztalk-host-receiving-throttled-because-processmemory-exceeded-the-configured-throttling-limit/#comment-2602
Even after changing the RL configuration , the Host Instance continuously consumes ~60% CPU.
Any suggestions to troubleshoot more on this issue ?
Thanks in advance !!
Anoop

This is one of the issue which has already been raised to Microsoft and hopefully a public build will be available soon in next cumulative update pack .
There are variety of reason for this starting for password mismatch or password not given , SFTP adapter unable to connect and so on .
There is good post here in below link for this issue
http://thoughtsofmarcus.blogspot.co.uk/2013/06/leaving-password-blank-in-biztalk-2013.html
Another greate artcicle is by Nino which states these issues .SFTP adapter is protocol sensitive and some configuration by server side, can cause a lot of crazy situations

SQL Server Analysis Services (SSAS) 2012 High Availability Solution in Azure VM

I have been testing an AlwaysOn high availability failover solution in SQL Server Enterprise on an Azure VM, and this works pretty well as a failover for SQL Server Databases, but I also need a high availability solution for SQL Server
Analysis Server, and so far I haven't found a way to do this. I can load balance it between two machines, but this isn't working as a failover and because of the restriction of not being able to use shared storage in a Failover Cluster in Azure
VM's, I can't set it up as a cluster which is required for AlwaysOn in Analysis Services.
Anyone else found a solution to use an AlwaysOn High Availability for SQL Analysis Services in Azure VM? As my databases are read-only, I would be satisfied with even just a solution that would sync the OLAP databases and switch
the data connection to the same server as the SQL databases.
Thanks!
Bill

Bill,
So, what you need is a model like SQL Server failover cluster instances. (before sql server 2012)
In SQL Server 2012, AlwaysOn replaces SQL Server failover cluster, and it has been seperated to
AlwaysOn Failover Cluster Instances (SQL Server) and
AlwaysOn Availability Groups (SQL Server).
Since your requirement is not in database level, I think the best option is to use AlwaysOn Failover Cluster Instances (SQL Server).
As part of the SQL Server AlwaysOn offering, AlwaysOn Failover Cluster Instances leverages Windows Server Failover Clustering (WSFC) functionality to provide local high availability through redundancy at the server-instance level—a
failover cluster instance (FCI). An FCI is a single instance of SQL Server that is installed across Windows Server Failover Clustering (WSFC) nodes and, possibly, across multiple subnets. On the network, an FCI appears to be an instance of SQL
Server running on a single computer, but the FCI provides failover from one WSFC node to another if the current node becomes unavailable.
It is similar to SQL Server failover cluster in SQL 2008 R2 and before.
Please refer to these references:
Failover Clustering in Analysis Services

SSAS High Availability in Azure (not SQL DBE)

Hello,
I was wondering what would be my options for having an SSAS environment with High Availability in Azure?
Please refrain from mentioning HA solutions for the SQL Database Engine itself - that is
not the issue at hand.
The issue is that as far as I know (and please correct me if I am wrong), the only way to provide SSAS HA is through clustering that involves share storage -- which is not available in Azure.
So I was wondering if anyone has come across such requirement before and if there are any sort of novel/original solutions
(thinking outside the box).
Regards,
P.

Hi Pmdci,
According to your description, you need implement SSAS environment with High Availability in Microsoft Azure, the problem is that you need to use share storage in this environment which is not available in Azure, right?
Based on my research, a clustered implementation of SSAS can be configured in Microsoft Azure.
A clustered implementation of SSAS can also span from on premises to Azure (or any qualified cloud) if networking is properly configured so that the nodes on premise and in the cloud can see each other, talk to Active Directory, and access storage.

Access Services 2013 high available on SQL 2012?

Hi,
Does anyone know how we get the randomly created databases from access services 2013 services high available on our SQL 2012 cluster?
For the SharePoint content databases, we use the ‘always on’ functionality of SQL 2012. This functionality is not supported for Access services 2013.
Thanks in advance,
Johan

Hi Edwin,
Thanks again for your answer.
Failover clustering is a perfect solution for high availability.
A last additional question:
Now we using ‘Always On groups’. The 2 instances are located one a different physical location.With that configuration, we have a High available solution and disaster recovery solution.
If we going for a Failover Cluster we have a High Available solution, but we don’t have a disaster recovery solution anymore because everything is located on the same physical location.
We can configure SQL mirroring, but then we have the same behavior like the ‘always On Groups’.-> Not possible to delete db’s from SharePoint and not automatically mirrored when created a new access services 2013 db.
Is there any solution/configuration to accomplish this?
Thanks,
Johan

High availability for Lync 2013 persistent chat server and office web app server

I have 1500 users, need HA in primary data center and DR also. looking for HA and DR solution for persistent chat server and office web app server.
is below correct?
1. 2 persistent chat server in a pool of primary data center and 1 in DR. can this be reduced or any changes?
2. 2 Office web app server in a pool of primary data center and 1 in DR. can this be reduced or any changes?
also do i need HLB for both roles?

1) In Lync Server 2013, there are improvements in both high availability and disaster recovery:
High availability improvements: SQL Server mirroring is used to provide high availability for the Persistent Chat Server content database and Persistent Chat compliance database within a data center (in-site).
Disaster recovery improvements: Persistent Chat Server supports a stretched pool architecture that enables a single Persistent Chat Server pool to be stretched across two sites (that is, a single logical pool in the topology, with servers in the pool physically
located across two sites). SQL Server Log Shipping is used for cross-site disaster recovery.
For more information about high availability and disaster recovery, see
Configuring Persistent Chat Server for High Availability and Disaster Recovery in the Deployment documentation.
2) for HA & DR, you can 2 Office web app server in a pool of primary data center and 1 in DR. and You will need HLB for office web app servers

Possible to use Azure SQL as database for RD Connection broker high availability?

I am looking in to setting up a highly available Remote Desktop services service on Azure and note that the high availability for the Connection Broker service needs a full SQL database (rather than the LocalDB used for one instance). Is it possible
to use an Azure SQL database for these purposes (i.e. opposed to VMs running SQL Server)?
Has anyone had any experience with this? This would be nice as I am not looking at thousands of users and the Azure SQL would provide the high availability for the database without creating multiple (expensive) VMs running SQL server.

So far there's no such a feature in azure sql, you can vote for it

Hi MAS,
Currently, I have only mailbox server and only database for each site.
+ Site1: I has DB1 and all users in site1 will access to their own site. (MBX1) subnet 192.168.1.0/24
+ Site2: I has DB2 and all users in site2 will access to their own site. (MBX2) subnet 192.168.2.0/24
But the email for incoming and outgoing with external will go to Site1.
In Planning,
I want to implement DAG to provide HA on database level below:
Is it possible to do that? dose it has any affected to current Outlook users?
