Some of the SOA foundations are: Loosely Coupled Reusability Stateless Services Formal contracts between Services Coarse Granularity Asynchrony Abstract Underlying logic (black box) Composable (services as building blocks) Discoverable services Autonomous services Most of them could be applied to Cloud Computing, so my question is...
Im looking at writing a application for a web 2.0 start up site which will essential monitor specific RSS feeds. Due to the expected up take of such a service I am expecting that taking advantage of cloud computing would be the way to do it, however with my lack of experience I do not know if it is possible to run a Windows service in t...
I'm hoping to reach someone with some experience using a service like Amazon's S3 with this question. On my site we have a dedicated image server. And on this server, we have an automatic 404 redirect through Apapche so that, if a user tries to access an image that doesn't exist, they'll see a snazzy "Image Not Available" image. We're...
OnLive is a cloud computing solution for gaming. It offers streaming of high-end games to any pc, regardless of its hardware. I wonder how it works: sending raw HD res image and audio data seems unlikely. Would relatively simple compression, like jpeg and mp3/ogg, do the trick? ...
I've got a fairly simple Windows service running on testbed EC2 nodes right now that basically: Calls a Web Service on a machine in our local data center when the service starts (the service is set to Automatic startup, so it runs when the instance comes online). Calls another Web Service once a minute as a monitoring heartbeat. Calls ...
There has been a lot of buzz around cloud technologies. What resources would you recommend that review the cloud computing world, and helps one get the big picture and current trends? In addition to reading these overviews, what would you recommend as first steps to get acquainted with these technologies? ...
I have been doing some catching up lately by reading about cloud hosting. For a client that has about the same characteristics as StackOverflow (Windows stack, same amount of visitors), I need to set up a hosting environment. Stackoverflow went from renting to buying. The question is why didn't they choose cloud hosting? Since ...
What are the best practices in building applications that support multiple tenants such as Software as a Service? Links to white papers that expand on this topic are greatly appreciated. ...
What do you see as the advantages and disadvantages of Amazon Web Services S3 compared with Google Application Engine? The cost per gigabyte for the two is, at the time I ask, roughly similar; I have not seen any widespread complaints about the quality of service; so I think the decision of which one to use may depend on the API (of all...
I am a keen follower in news related to Amazon S3. It seems to be reliable, scalable and a cheap service. However, web hosts do not seem to be overly scared. I have not noticed any major drops in prices since Amazon and Google released their 'Cloud' based platforms. Is there a reason for this? Or are web developers simply not aware of ...
I'm looking for a cloud computing service with the following requirements: no need to manage servers instant availability automatic scaling ability to run tasks for at least a couple of minutes Google App Engine seems to meet all of these requirements with the exception that processes can only run for 30 seconds. My application is a...
I'm working on a Google App Engine application, and have come to the point where I want to associate images on the filesystem to entities in the database. I'm using the bulkupload_client.py script to upload entities to the database, but am stuck trying to figure out how to associate filesystem files to the entities. If an entity has th...
How and when do you decide which cloud service is best? EC2 offers Virtual Servers, but can be a pain in some cases, and overkill as well. Azure is great for web apps written in ASP.NET, while GAE is good for Python users, but neither offers the low level of EC2. So, how do you decide where you go? ...
I'm thinking about developing a framework to simplify running distributed computations in .NET cloud environment of Windows Azure. Azure currently (and by the time of the release, most likely) is completely unsuited for simple running of distributed queries in the cloud (details). Simple for me is something like DryadLINQ where you can...
Our company is considering moving from hosting our own servers to EC2 and I was wondering if this was a good idea. I have seen a lot of stuff about can cloud computing (and specifically EC2) do x, or can it do y, but my real question is why would you NOT want to use it? If you were setting up a business, what are the reasons (outside o...
Hi guys, So far, my https deployments have commonly involved a naive lockdown of the entire site with https and provide an http-to-https redirect on the web server. I now plan to have a single ASP.NET MVC site (on the cloud) that will contain both http and https pages. So, the site will have 2 conceptual (not physical) zones providing ...
Who is using Cloud Computing like Windows Azure, Google Apps Engine, Amazone S3 ... and what are you using it for? Why don't you use dedicated Servers or in-company infrastructure instead? Do you know a Company that uses CC? ...
Is it possible to deploy service in the cloud , which does not use standard http protocol for providing services ?. Basically I have requirement to write service which does not use http to exchange messages between client/server. It is traditional client server application , which uses non standard protocol running on port other than por...
We're in the process of migrating from a datacenter to Amazon. We're a small company and rather than upgrade our hardware, we've found it to be enticing to move to "the cloud." We've put together custom AMI's from scratch and are currently in process of deciding on how to configure the environments. I've been using Amazon's management c...
Say I have a site like stackoverflow. I need to add a search functionality, I need it to be good. I don't care if I have to add a logo (like if I am using a google search). What options do I have, with minimum of development and minimum server type dependency. I am currently on Lamp (php). EDIT: Pardon, but I am talking about an open...
