  • Apps can grow especially fast on social networks, so before you launch your next social app, you should think about how to scale up quickly if your app takes off.
  • Unfortunately, scaling is a complex problem that's hard to solve quickly and expensive to implement.
  • If this app grows to serve millions of users and photos, shared hosting or even a dedicated server won't have the bandwidth or CPU cycles to handle all of the requests. We could invest in more servers and network infrastructure, shard the database, and load-balance requests, but that takes time, money, and expertise. If you'd rather work on the new features of the app, it's time to move into the cloud.

  • It's important to focus on the interactions between the app and your server when designing an application that will run in the cloud. If we standardize the communication protocol and data format, we can easily change the server side implementation without modifying the OpenSocial app.
  • You can configure the makeRequest method to digitally sign the requests your app makes to your server using OAuth's algorithm for parameter signing. This means that when your server receives a request, it can verify that the request came from your application hosted in a specific container. To implement this, the calls to makeRequest in the OpenSocial app spec XML specify that the request should be signed, and the code that handles requests on the server side verifies that a signature is included and valid
  • When our server receives a request, we can verify that it came from our application by checking that the digital signature was signed by a valid container and that the application ID is correct.
  • Since our server isn't storing any relationship data, the app will need to send us a list of user IDs so we can fetch the appropriate photos.
  • Although it's outside the scope of this article, we could provide a mechanism for our OpenSocial app to request a one-time-use token that it would include in the request to upload a photo.
  • Note that the post data is URL-encoded in the request so the post method uses urllib.unquote before splitting the comma-separated list of person IDs.
  • Since the server doesn't store any relationship data, the PhotosHandler class checks the post data of the request for a list of IDs from the container.
  • A common misconception when coding in the cloud is that storage space, CPU cycles, and bandwidth are unlimited. While the cloud hosting provider can, in theory, provide all the resources your app needs, hosting in the cloud ain't free so these resources are limited by your budget. Luckily, OpenSocial provides several mechanisms to cache images and data that will reduce the load on your server.
  • In addition to reducing traffic to our server, this technique has the added benefit of being fast—requesting data from the Persistence API is much faster than making the round trip to your server.

    Some OpenSocial apps can be written entirely with client-side JavaScript and HTML, leveraging the container to serve the page and store application data. In this case, the app can scale effortlessly because the only request hitting your server is for the gadget specification which is typically cached by the container anyway. However, there are lots of reasons to consider using your own server: * Allows you to write code in the programing language of your choice. * Puts you in control of how much application data you can store. * Lets you combine data from users on multiple social networks. * Enables interaction with the OpenSocial REST API. Setting up an OpenSocial app that uses a third party server is fairly simple. There are a few gotchas and caveats, but the real issues come up when your app becomes successful - serving millions of users and sending thousands of requests per second. Apps can grow especially fast on social networks, so before you launch your next social app, you should think about how to scale up quickly if your app takes off. Unfortunately, scaling is a complex problem that's hard to solve quickly and expensive to implement. Luckily, there are several companies that provide cloud computing resources-places you can store data or run processes on virtual machines. These computing solutions manage huge infrastructures so you can focus on your applications and let the "cloud" handle all the requests and data at scale. This tutorial focuses on a simple photo-sharing app that uses a third-party server to host photos and associated metadata. If this app is going to host millions of images and support many requests per second, we won't be able to run it on a single dedicated host. We'll break the app down and analyze the interactions between the OpenSocial App and the back end server. Then we'll implement the app in the cloud, first using Google App Engine, then leveraging Amazon's S3 data storage service. Finally, we'll look at s

    Price cuts from Amazon, Google and Microsoft support predictions that the public cloud computing market is a race to the bottom -- for pricing, that is. Customers will no doubt benefit, but cloud providers who aren't one of those three companies should be prepared for a long, hard war of attrition.

Susan Brenner: "Privacy and the Cloud" - 1 views

Brenner privacy legislation cloud

shared by Stian Danenbarger on 20 Aug 09 - Cached
  • the 4th Amendment was developed at a time when the only privacy was spatial privacy; for something to be private, I had to keep it IN my home or office (and maybe in a locked chest), which both made it difficult for law enforcement officers to gain access to it and symbolically invoked my right to assume they wouldn’t gain access to it. (In other words, I could assume privacy.)
  • our lives have already moved far beyond spatial privacy; I talked about the 4th Amendment’s application to the contents of emails and what we do online -- arguing that it should apply to both, but noting that courts so far do not tend to agree. I think cloud computing will take this analysis to the next level.
  • My point is that even under current 4th Amendment law, I can make what I think are valid arguments as to why the 4th Amendment should apply to data stored in a cloud (as long as the appropriate conditions exist). I really think, though, that we shouldn’t be using cases that were decided thirty years ago or a hundred and thirty years ago to set the standard for 4th Amendment privacy in an era of advancing technology. As I argued in that law review article, I think we need to move beyond a purely spatial approach to privacy to approaches that encompass both spatial and non-spatial privacy.

    What about privacy in an era of cloud computing? If I store my data in a cloud, is the data in a "closed container" and therefore private under the 4th Amendment? Or is putting data in a cloud analogous to giving the numbers I dial on my phone to the phone company?

    This document is intended to initiate a conversation that will bring together the emerging cloud computing community (both cloud users and cloud providers) around a core set of principles. We believe that these core principles are rooted in the belief that cloud computing should be as open as all other IT technologies.

  • Young said IT managers considering a move to the cloud should ask the following questions, for starters: --How portable is the technology and data across international borders? --Who is backing the service provider? --Is the provider certified, and by whom? --Where does the data originate? --How is the identity management process set up? --Who manages physical security at the provider's facilities? --How is change management handled? --What happens to your partnering model?
