I am really blessed to be part of Lionbridge SaaS team, the knowledge they brought within me about SaaS is incredible. I would not be writing this article if I was not the part of the team. Here’s nice article from the same team on SaaS http://www.lionbridge.com/lionbridge/en-US/kc/product-engineering/configurability-in-saas.htm . The article by Modesty zhang really inspired me to write this article, here’s a reference http://www.codeproject.com/KB/silverlight/Azurelight.aspx , thanks for bringing the Azure interest in me.
Yes, worker role cannot connect take inbound calls from internet but it can make outbound calls. A worker role is background processing process so it does not have incoming internet requests. Worker role also has access to queue services. So that can be one more communication point where external systems can post data and worker role can read from the same.
Queues: – Queues are used enable asynchronous communication. They are enabled to store transient data in form of messages. Azure uses queues to communicate between different entities. For instance of a worker role and web roles wants to communicate they use queues. We will be discussing the above 3 things in more detail in the coming FAQ series. We will be dedicating each one of them a complete FA series. Till then hold your breath.
No we cannot use standard SQL to query the above azure storages. They are accessed through REST (Representational state transfer). REST is a style of software architecture distributed systems. So if you want to read a data from a table you need to specify the below URL. http://<
So use Azure storage:- • If your application is having a massive scale. • You are not looking for rich relational data functionality like SQL, structured relational tables etc. • You are looking for a less cost. You need to use SQL Azure service • Scalability is not the important factor. • You are looking for rich database functionalities like SQL, structured relational tables etc. • Cost is not a big matter.
