Snapshot process is faster in Docker than VMs

Is it possible to use Dropbox, Google Drive, Skydrive, etc. as a server space?

独自空忆成欢 提交于 2019-12-03 08:57:19
I'm creating an app that connects online to a server to collect information. To save money from renting server space from a big corp, I was wondering if any of these free services (Dropbox, Google Drive, Microsoft Skydrive, Amazon Cloud, etc.) could be potentially used as server space? I pretty much want a "space" or "cloud" where people can connect to to collect data. Example: I have a weather app, and there is files on my server and I update the files according to the weather. I would like them to be able to open the app and connect to my server to gather the weather data saved on my server.

How to automatically send print job from “Cloud” server to printer?

给你一囗甜甜゛ 提交于 2019-12-03 08:55:43
A picture is supposed to be worth a 1000 words, so let's see if that can shorten this post up a bit... Essentially, I'm looking into "how" to code a solution that runs on the web server within the cloud that will send a print command to a printer within office 1 (label printer). The print job is really part of work flow within the ASP.NET web application and I would like to keep all of the code within a single application if possible. How can I go about doing this? Due to security, I should avoid creating a new application within Office 1 that pulls data from the "cloud" and have the "cloud"

Difference Between Virtualization and Private Cloud Computing [closed]

I am confused with virtualization and private cloud computing. What do they serve for? Their purposes? Can they be combined, let say we build virtualized servers on private cloud? From what I understand, cloud computing embraces the idea of IaaS (infrastructure as a service). In other words, I could start with minimal number of bare metal servers and expand it as requirement needs, and those servers are consolidated into one big machine through divided computing and data storing. Being said that, can we build virtualization on the private cloud? For example, I might buy like 10 servers

Why randomize your file names for cloud storage/CDN?

When you look at a profile picture on a social networking site like Twitter, they store image files like: http://a1.twimg.com/profile_images/1082228637/a-smile_twitter_100.jpg or even with a date somewhere in the path like 20110912. The only immediate benefit I can think of is preventing a bot from going through and downloading all files in your storage in a linear fashion. Am I missing any other benefits? What is the best way to go about randomizing it? I am using Amazon S3 so I will have one subdomain serving all my static content. My plan was to store an integer ID in my database and then

How can I access s3 files in Python using urls?

心不动则不痛 提交于 2019-12-03 08:26:24
问题 I want to write a Python script that will read and write files from s3 using their url's, eg:'s3:/mybucket/file'. It would need to run locally and in the cloud without any code changes. Is there a way to do this? Edit: There are some good suggestions here but what I really want is something that allows me to do this: myfile = open("s3://mybucket/file", "r") and then use that file object like any other file object. That would be really cool. I might just write something like this for myself if

Relative advantages of storage using Amazon Web Services S3 vs Google Application Engine

|▌冷眼眸甩不掉的悲伤 提交于 2019-12-03 07:41:18
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 things). Google's API breaks your content into what they call static content, such as your CSS files, favicons, images, etc and non-static dynamically-generated HTTP responses. Requests for static stuff will be served to whoever requests it until your bandwidth

Cloud computing over Client-server: differences, cons and pros? [closed]

Closed . This question is opinion-based. It is not currently accepting answers. Learn more . Want to improve this question? Update the question so it can be answered with facts and citations by editing this post . As far as I know, Cloud computing might be a evolution in software architect, and it will replace some current architectures, such as client-server. These two architecture seem to share similarities for me (I know very little about both), but I don't know the differences between them. What are the cons and pros of cloud computing over client-server architecture? Thank you so much.

Azure cloud service project configuration (.csdef and .cscfg) in multiple environments

走远了吗. 提交于 2019-12-03 05:47:37
Currently we have a development cloud services (acme-dev-service) and a production cloud service (acme-prod-service). Our current setup in our solution has a cloud service project called acme.application that uses transformation of the .cscfg and .csdef files for deploying the project to the two environments (production and development). I don’t like the transformation method because it feels like a bit of a hack to me. So after doing some research it seems that you can have multiple configuration files which solves some of the issue but I am running into problems because you are only allowed

Renamed Heroku's hostname, now it can't find the application

柔情痞子 提交于 2019-12-03 05:44:14
I previously had my Heroku's application name at: shielded-meadow-9293.heroku.com This was the name when I created the Heroku remote and fired up the dyno. After everything was running smooth, I changed the name to platformdesignmadness.heroku.com The site works, but in the same terminal, when I do a command such as heroku ps I get a $> ! Couldn't find that app. error. Why is this? Alex In your terminal: git remote rm heroku git remote add heroku git@heroku.com:yourappname.git See here Heroku docs here .
