问题 I want to host my WCF services in the Azure clouds for scalability reasons. For example there will be service for user authentication. And it will be under High Load (1000+ user/sec). Does anybody here have real experience with hosting WCF services in the Azure cloud with high user load? What are best practice, patterns here? Does Azure has some cloud balancing API for such tasks? Thanks, Kirill. 回答1: EDIT April 9, 2014 - updated with latest scalability targets The Windows Azure load balancer

问题 I need to migrate a huge application to Windows Azure. The application depends on a third-party library that requires an activation key stored in a special binary file on the role instance filesystem. Obviously that key has to be either included into the role package or stored somewhere where role can fetch it. The activation key will not be bound to the machine (since I have no idea where exactly a role will be run in the cloud) so anyone can use it to make a copy of that library work. Since

问题 I see that we now have both Windows Server AppFabric and Azure AppFabric. Is this just a namespace collision in the Microsoft marketing department or do these technologies share common interfaces? Someone told me that is was possible to run an application using Azure AppFabric on a local production server, then change the deployment target to Azure on demand. Is this possible and consistent with Azure licensing? If so, can we use Windows Server AppFabric on the local server in this scenario?

问题 Is Azure an appropriate/viable platform for a process that receives various encrypted and/or compressed files, extracts them, and manipulates them? For example, I currently have a process that uses SSIS to download flat files as described above and loads them to a database. New files are then extracted and gzipped or PGP encrypted and FTP'd out. If I was to migrate this process to Azure + SQL Azure, what is the best way to go about this? I have a front end that allows files to be posted to

问题 In loopback framework, we have a module LoopBack Storage Component. It's support for many clouds except Google Cloud Storage. But I have to use Google Cloud. 回答1: It should support Google out of the box because it uses pkgcloud lib which has support for Google Cloud. Try simply adding a config entry to the providers.json file. For more info on how to do that check Loopback storage component documentation and also pkgcloud config format for Google Cloud. I'd just try something like this in the

问题 We have a solr cloud setup of 4 shards (one shard per physical machine) having ~100 million documents. Zookeeper is on one of those 4 machines. We encounter complex queries having wild cards and proximity searches together and it sometimes takes more than 15 secs to get top 100 documents. Query traffic is very very low at the moment (2-3 queries every minute). 4 Servers hosting cloud have following specs: (2 servers -> 64 GB RAM, 24 CPU cores, 2.4 GHz) + (2 servers -> 48 GB RAM, 24 CPU cores,

问题 The web service that I want to run on AWS has to store and retrieve user data, present it to the user via a website, and needs to be able to parse the sitemaps of a few thousand sites every 10 min or so. Which components of AWS, such as S3, EC2, and CloudFront do I need to use. A short synopsis about the purpose of each component would be nice. :) I particularly do not understand the purpose of the Simple Queue Service. 回答1: You might, for example, use EC2 (on-demand, scalable, VPS) to host

问题 In the past few months our snapshots backup volume increases and hence our monthly bill in amazon EC2. Now i wanted to delete some of our old EC2 snapshots. So here is the question: How to find all the snapshots created from a single Volume ID using EC2 command line tool? I tried ec2-describe-snapshots but this list all the snapshots. We have lots of snapshots and it is very difficult for me to note them down one by one. 回答1: aws ec2 describe-snapshots --filters "Name=volume-id, Values=vol

问题 I have a Apple Developer account, BUT I don't have a Mac, and I need to do the following with my Ionic project: Package a native Ionic iOS app AND Publish it to the Apple Store. I've read about the limitations to compiling and publishing an iOS app in the Apple Store without a Mac, but I am in doubt about the Ionic pro. There says that Ionic pro can 'Package native app builds in the cloud' , but does this mean that I can publish the generated cloud Package from Ionic Pro directly to the Apple
