Could anyone help me to understand blades, racks, clusters in azure and how they are related. Not sure from where to start.
its a cloud platform. there are no blades,racks and clusters. there are resources. you dont care about underlying hardware.
only thing that matters - Fault and Upgrade domains. Read here.

Hello to the Best Community ever!
I'm facing some performance problems with Azure SQL elastic pool. Thank you for reading!
The picture... i'm migrating to Azure our systems. Part of our core business is written in 32 bits applications. I believed that the Azure Sql elastic pool would be a good choice, but the performance run down x3. I think that the problem is how these 32bits apps negotiate the connection with the database. Also tried several MS's ODBCs and third party drivers. Devart´s one, for example. Without success. XS
I'm writing this hoping someone had the same issue and solved it. MS don't give us much support and refactoring the code is not an option right now.
The walkthrought is to install several virtual machines with sql servers and re-migrate from elastic pool. But that would take more time including replannification.
I hope this is all about configuration and/or finding the correct driver...
I hope this thread finds you.
Thank you!
I´m planning a new web-project and want to implement node.js microservices. Now I´ve read a lot and found out that it will be a recommended way to do that with docker/kubernetes for availability and scaling.
It will be my first project and a have a lot of question now. Hopefully the community helps me out a bit with it:
Kubernetes-Cluster:
One of my first questions is the cluster. What is the best way to start with the cluster? Azure AKS is mostly used in web-tutorials, but isn´t it possible to start with an own server installing Docker and Kubernetes via a webhosting?
My biggest problem is that I don´t know to to calculate prices on Azure. For me it is clear that the cluster hasn´t any costs, but how do I calculate VM and Traffic.
And what about having a lot of API´s, should be each API an own AKS-Service on Azure = 1 VM which is 24 hours up and running?
It should be a webproject, all API´s must be available 24 hours.
Has anyone experiences with using Azure AKS with an similar project and has some explanations for me.
If it is possible with an webhosting package, has someone a tutorial how to start with it?
Thanks to all for help, hopefully there is someone to clarify some points for me.
According to #Bricktop -Please start using Kubernetes to get practice:
Locally:
Minikube
Kubeadm
In cloud (please create free account) you can find more details below:
Gcloud
Azure
AWS
After getting some knowledge about your solution, how it works what resources are necessary (related to this project - please use monthly billings provided by the Cloud-provider of your choice. You can use also "Pricing Calculator" from the official websites.
Hope this help
I'm trying to come up with a solution for achieving Geo-Redundancy (2+ datacentres) while using Service Fabric reliable Actors/Services to manage state. It insinuates here that geo replication is possible
This may happen when, for example, if you aren’t geo replicated and your entire cluster is in one data center, and the entire data center goes down.
but doesn't explain how to switch it on.
Does anybody know if it's a planned feature for ASF that just hasn't been released yet, or whether it's present but not fully explored yet?
Alternatively does anybody have any recommended approaches for cross DC resilience when the state required to run the app is stored using ASF's StateManager?
thanks,
Alex
Alex,
Apparently the service fabric team is still to crack this problem - more info below. However, you should be able to GeoHA Service Fabric Cluster on Azure by yourself. Here's an example of that:
https://alexandrebrisebois.wordpress.com/2016/05/31/deploy-a-geo-ha-service-fabric-cluster-on-azure/
Not today, but this is a common request that we continue to investigate.
The core Service Fabric clustering technology knows nothing about Azure regions and can be used to combine machines running anywhere in the world, so long as they have network connectivity to each other. However, the Service Fabric cluster resource in Azure is regional, as are the virtual machine scale sets that the cluster is built on. In addition, there is an inherent challenge in delivering strongly consistent data replication between machines spread far apart. We want to ensure that performance is predictable and acceptable before supporting cross-regional clusters.

Cheers,
Paulo
There is no reason you cannot install a series of nodes in different regions as part of the same Fabric, and use placement constraints to control service allocation. As long as the nodes can properly communicate with each other, there should be no problem with this.
If you're using Azure, you should deploy them to Virtual Networks, and link them together using VPNs. You could even cross to on-prem.
I believe the answer would be to use a custom replicator implementation and bridging multiple clusters with expressroute.
I have developed an enterprise level application(CRM), And planning to provide it as a SAAS/Hosted Solution.
I am very much worried about the Server & It's Architecture to handle the large traffic. I did some work and reached at, I can use AWS Or Rackspace Claude Service with Load Balancer, RDS, S3.
But still I am not sure it is enough to handle the large traffic or not. I have following questions please provide me some suggestion.
Is there any other good Cluod Service provider than AWS and Rackspace.
How to architect the server(Backup Plan, Highly Available, Data Base Server, Staging etc.)
Please suggest some tool to monitor the server performance.
Server Security.
Tools to calculate the server costing.
Thank You
Is there any other good Cluod Service provider than AWS and Rackspace. - There are options like Google Cloud, HP Cloud, SoftLayer, Azure and many more.
How to architect the server(Backup Plan, Highly Available, Data Base Server, Staging etc.) - Pretty big question to address.
Please suggest some tool to monitor the server performance. -- NewRelic can be one of them.
Server Security. -- Pretty big question to address.
Tools to calculate the server costing. -- https://planforcloud.rightscale.com/ - This would help.
I am about to deploy a nfs-like shared storage on AWS infrastructure that will be accessed by about 10-15 linux servers. What I could just check is that AWS doesn't provide such solution (at least as I know we can't plug an ebs on more than 1 server), I just tried to use some s3-fs but I haven't trusted any of the available solutions as since as all of them seems to be too unstable. What have you guys been using that could deliver some performance and at same time security?
All suggestions are welcome, I would appreciate it a lot.
Thank you!
