Cloud Hosting/Storage Toolbox: Options & Tools

Post pobrano z: Cloud Hosting/Storage Toolbox: Options & Tools

Cloud IconCloud hosting, storage & content delivery networks (CDNs) are very popular services for the last few years, which is very normal, as they offer a series of advantages in running + serving web applications.

An application hosted in the cloud will:

  • easily scale (with instantly deployable & API controlled instances, unlimited diskspaces, etc..)
  • serve files faster with content delivery network (CDN) support
  • have a better availability (with strong SLAs)

With the increasing number of providers & tools created, cloud hosting is getting simpler & simpler everyday.

Getting in the cloud, in most cases, will save so much time & resources when running a growing web application. You won’t need to think of the hardware, better react to the system resources & bandwidth usage fluctuations, pay exactly for what you use & much more.

Here is a collection of popular options & tools that can help you in hosting your applications in the cloud:

 

Cloud Hosting & Storage Options


Amazon Web Services (AWS)

Amazon Elastic Compute Cloud (Amazon EC2) – (hosting)

Amazon EC2

Amazon EC2 is a web service that provides you the environment to instantly launch (or remove) new servers (instances) with the OS & configuration you need which makes scaling of a web application much easier.

This functionality can be controlled via the web service APIs or tools to be mentioned in this post.

You are charged with the resources consumed like hours your servers (instances) work or the bandwidth used.

Amazon Simple Storage Service (S3) (storage)

Amazon S3

Amazon S3 is the cloud storage option of AWS where unlimited number of files can be stored & retrieved.

It can be used with the API provided or various tools (mentioned in this post).

Pricing of the service is calculated with the number of requests made, amount of data stored & bandwidth used (transfers between EC2 & S3 are free)

AWS also offers other services that power (or powered by) EC2 & S3:

  • Amazon CloudFront: content delivery network which enables faster delivery of files hosted on S3 to end users by distributing the files to various locations.
  • Amazon CloudWatch: monitoring for EC2 resources like CPU, RAM, disk read/writes & more.
  • Amazon SimpleDB: a simple web based database which provides basic db functions.

Google App Engine (hosting)

Google App Engine

Google enables developers to host their applications inside its own infrastructure. And besides many other cloud hosting systems, Google doesn’t provide you root access but gives the possibility of unlimited resource usage.

The platform supports 2 languages: Python & Java. But there are tricks to run other languages in the engine (Run PHP on the Google App Engine).

The service comes with a free quota where a basic application can be easily hosted for free. For over-quota, the pricing is applied.

Created instances can be standalone or integrated with other SoftLayer dedicated servers, virtual servers, automated services, and additional CloudLayer Services which makes the usage highly flexible.

Instances can be reached via KVM over IP & managed via an API or the web-based control panel.

CloudLayer Storage – (storage)

The cloud storage of SoftLayer can be reached via API, a native Windows client, WebDav, or mobile devices. The system also integrates with CloudLayer CDN which offers fast delivery of content from 21 locations around the world.

Clixpy: A Practical Web Service To Capture User Activities (50 Free Promo Codes)

Post pobrano z: Clixpy: A Practical Web Service To Capture User Activities (50 Free Promo Codes)

As designers & developers, we try to make a website easier-to-use for end-users. This can be building a less-complicated system, using different sizes & colors according to the priority of the content, etc.

But, whatever we do, we need to findout if these work or not. Because sometimes, users do the unexpected & surprise you with "how the easy-to-use website you created" is not easy for them.

Clixpy

Clixpy, a very easy to install & use web usability testing tool, is a great helper for finding out how users browse a website. It does this by recording the activities of:

  • mouse movements
  • clicks
  • scrollings
  • form inputs

A statistics application can give you the browsing route of a visitor. But, it does not provide what happens at that route & why readers choose that route, which actually are the vital questions. And this is what Clixpy offers.

How to install & use it?

A JavaScript code inserted into a website’s footer is automatically detected by Clixpy & tracking/recording starts (will be great if it becomes possible to limit the websites that can use the code to prevent unexpected usages).

From the admin interface of the application, you can filter the sessions recorded by domain, date or the status (new captures, atched ones, etc.).

Before viewing a session, you can have a strong idea about the details of it as Clixpy displays the number of pageviews, which pages are viewed, duration & user + browser details captured. It also enables you to save & take notes on any capture to analyze them later.

Clixpy Session Player

By clicking on any captured session, Clixpy presents you the same experience the reader has on the website.

Also, you can define a limit on the capturing process like "capture first 20 sessions" or "stop the whole capture feature anytime".

What to expect as a result?

After installing Clixpy & capturing the sessions of your visitors, it is time to analyze the results. Simply:

  • watch the sessions
  • see which features your visitors find difficult & easy to use
  • take notes
  • & take action, fix the parts that you can offer a better user experience. And, for a double check, re-capture those webpages with Clixpy to see if the updates really work.

50 free promo codes with 100 captures each

Clixpy is offering 50 free promo codes to WebResourcesDepot readers for tasting the application. Each promo code enables you to capture 100 sessions. To get one, besides any comment you might have, simply mention "I want a discount code" in the comments & one promo code will be e-mailed to you within a day.

All promo codes are now requested. But don’t worry, you can always play with Clixpy’s demo to see how it works.
