What's the difference between BigQuery and BigTable? [closed]

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 months ago . Is there any reason why someone would use BigTable instead of BigQuery? Both seem to support Read and Write operations with the latter offering also advanced 'Query' operations. I need to develop an affiliate network (thus I need to track clicks and 'sales') so I'm quite confused

What does ECU units, CPU core and memory mean when I launch a instance

一笑奈何 提交于 2019-12-03 00:58:34
问题 When I launch an instance on EC2, it gives me option for t1.micro, m1.small, m1.large etc. There is a comparision chart of vCPU, ECU, CPU cores, Memory, Instance store. Is this memory RAM of a system ? I am not able to understand what all these terms refer to, can anyone give me a clear picture of what these terms mean ? 回答1: ECU = EC2 Compute Unit. More from here: http://aws.amazon.com/ec2/faqs/#What_is_an_EC2_Compute_Unit_and_why_did_you_introduce_it Amazon EC2 uses a variety of measures to

Cloud Foundry explained

问题 So I've been reading up on Cloud Foundry and yet I'm still confused as to what it is. Here is my take anyway on PaaS on CF, and hopefully you guys could tell me if I'm wrong and explain it a bit better. A traditional PaaS offering like Microsoft Azure or Google AppEngine provides a full platform to develop, test, host and manage your web app. You must however use their API and are restricted to the services that they offer and languages/frameworks that they support. Cloud Foundry seems to be

Mixed http/https site

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 for both secure and non-secure requests. Configuration-wise, I have set up input ports for both 80 and 443 and the site accepts both requests. Is there any way I can flip protocol to https for any call that goes to an action that belongs in the secure zone? For instance,

Google BigQuery Underlying Architecture

泪湿孤枕 提交于 2019-12-03 00:20:23
So I just started messing around with Google BigQuery about 10 minutes ago, and I was wondering if anyone is aware of the underlying architecture that they're using to store the data? For example, is this just the next generation of their own BigTable infrastructure? Also, is it clear what sorts of strategies they're using for indexes, index rebuilds, etc? I'm just trying to analyze whether this is mature enough at this point where you can be 100% sure of what's going on with your data end-to-end, or is there a bit of a black box area where "things just work"? There are no indexes... every

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . What are the significant differences between Cloud Computing and Grid Computing ? What are the precise definations and target application domains for both ? I'm looking for conceptual insights along with technicalities. Like Windows Azure is a Cloud OS, do we have anytihng such for Grid Computing ? In past I did

When should one use the following: Amazon EC2, Google App Engine, Microsoft Azure and Salesforce.com?

问题 I am asking this in very general sense. Both from cloud provider and cloud consumer's perspective. Also the question is not for any specific kind of application (in fact the intention is to know which type of applications/domains can fit into which of the cloud slab -SaaS PaaS IaaS). My understanding so far is: IaaS: Raw Hardware (Processors, Networks, Storage). PaaS: OS, System Softwares, Development Framework, Virtual Machines. SaaS: Software Applications. It would be great if

How can I access s3 files in Python using urls?

↘锁芯ラ 提交于 2019-12-02 23:47:40
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 it doesn't exist. I could build that abstraction layer on simples3 or boto. For opening, it should be

start working with cloud computing

我的梦境 提交于 2019-12-02 23:37:23
问题 I am very new to cloud computing. I was wondering can i develop a website using LAMP stack on cloud. And which cloud to use. Is there any open source cloud out there to use it. 回答1: Sort of. You can use Eucalyptus to develop applications that would run on Amazon's EC2 using the LAMP stack. Eucalyptus is open source. Everything you run on an EC2 instance can be open source, but the actual EC2 instance is paid for (if that's what you were trying to avoid). EC2 is cloud computing in the Hardware

What are the differences between a VM image and a Docker image? [duplicate]

This question already has answers here : How is Docker different from a virtual machine? (19 answers) Are there any differences in images of Docker and Virtual Machine? Except the image formats, I couldn't find any info on this anywhere. Please comment out on the things like image size, instance creation time, capture time, etc. Thanks! devesh-ahuja These are some differences between a docker and a VM image which I could list out: 1. Snapshot process is faster in Docker than VMs We generally start with a base image, and then make our changes, and commit those changes using docker, and it
