Set Up Amazon WorkSpaces - Step by Step Process

This article covers how to set up Amazon WorkSpaces for our customers. Amazon WorkSpaces is a managed, secure Desktop-as-a-Service (DaaS) solution. With Amazon WorkSpaces, your users get a fast, responsive desktop of their choice that they can access anywhere, anytime, from any supported device.

With Amazon WorkSpaces, you can provision virtual, cloud-based Microsoft Windows or Amazon Linux desktops for your users, known as WorkSpaces.

Generally, Workspaces are meant to reduce clutter and make the desktop easier to navigate. Workspaces can be used to organize your work. For example, you could have all your communication windows, such as e-mail and your chat program, on one workspace, and the work you are doing on a different workspace.

The Amazon WorkSpaces Free Tier provides two Standard bundle WorkSpaces with 80 GB Root and 50 GB User volumes, running in AutoStop mode, for up to 40 hours of combined use per month, for two calendar months, from the time you create your first WorkSpace.


Key Features of Amazon WorkSpaces:

1. The end-users can access the documents, applications, and resources using devices of their choice such as laptops, iPad, Kindle.

2. Network Health Check-Up verifies if the network and Internet connections are working. Also, checks if  WorkSpaces and their associated registration services are accessible, and checks if port 4172 is open for UDP and TCP access or not.

3. Client Reconnect feature allows the users to access their WorkSpace without entering their credentials every time when they disconnect.

4. Auto Resume Session feature allows the client to resume a session that gets disconnected due to any reason in network connectivity within 20 minutes by default. This can be extended for 4 hours. However, the users can disable this feature any time in the group policy section.

5. Console Search feature allows Administrators to search for WorkSpaces by their user name, bundle type, or directory.


Some AWS Limitations:

1. AWS service limits. AWS service limits are set by the platform.

2. Technology limitations. An exceptional characteristic of this limiting factor is that it can be applied to all Cloud services, not just on AWS.

3. Lack of relevant knowledge by your team.

4. Technical support fee.

5. General Cloud Computing issues.

Amazon Redshift - Its features and how to set it up

This article covers an effective method to set up Amazon Redshift. Amazon Redshift is a fully managed, petabyte-scale data warehouse service in the cloud. This enables you to use your data to acquire new insights for your business and customers. The first step to create a data warehouse is to launch a set of nodes, called an Amazon Redshift cluster.

Amazon Redshift is a relational database management system (RDBMS), so it is compatible with other RDBMS applications. Amazon Redshift and PostgreSQL have a number of very important differences that you need to take into account as you design and develop your data warehouse applications.

Amazon Redshift is based on PostgreSQL.

Amazon Redshift is specifically designed for online analytic processing (OLAP) and business intelligence (BI) applications, which require complex queries against large datasets.


What is the difference between Amazon Redshift and Amazon Redshift Spectrum and Amazon Aurora?

Amazon Simple Storage Service (Amazon S3) is a service for storing objects, and Amazon Redshift Spectrum enables you to run Amazon Redshift SQL queries against exabytes of data in Amazon S3.

Both Amazon Redshift and Amazon RDS enable you to run traditional relational databases in the cloud while offloading database administration. 

Customers use Amazon RDS databases primarily for online-transaction processing (OLTP) workload while Redshift is used primarily for reporting and analytics.

Set up Amazon CloudFront with WordPress site - Do it now

This article covers how to set up Amazon CloudFront with WordPress site. WordPress performs reasonably well out of the box, but there is room for improvement—the number of WordPress plugins that address performance is evidence of this.  However, the easiest way to improve the user experience is to accelerate one's entire WordPress website by using CloudFront. 

Doing this will not only improve your site's responsiveness, but it may also reduce the overall cost of operating your WordPress infrastructure, as reducing the load on your web servers may help you scale down the required infrastructure. 

In fact, CloudFront can significantly help your site cope with an unexpected load when your site gets popular.


How does CloudFront help?

Many AWS customers have users spread across the globe that they want to reach. However, what once required an immense engineering effort can now be easily built using AWS Regions and Edge locations, which allow you to serve content from the locations closest to those users.

Data transfers on the internet depend largely on global networks of fiber optic cables, allowing very high bandwidth data transfers. 


As the speed of light is proving a difficult challenge to overcome, Amazon CloudFront improves the experience for users accessing your websites in several other ways, including:

1. Anycast DNS ensures your customers are routed to the nearest edge location.

2. Cached content, when available, is delivered to your users from the edge location.

3. When data needs to be fetched from your site CloudFront optimizes network throughput by managing the transfers between Edge Locations and your website.  This traffic runs over the Amazon Global Backbone, where optimized TCP configuration ensures more bytes are in-flight on the network, improving throughput, while TCP connection re-use eliminates much of the latency associated with establishing connections.   In this way, whether content is cached or not, it will be accelerated by delivery over optimized network paths.

4. Finally, negotiating and offloading Transport Layer Security (TLS) at the CloudFront Edge further improves performance, reducing connection setup latency, and further supporting back-end connection re-use.

How to setup AWS CloudFront and how it delivers content

This article covers how to setup AWS CloudFront. Basically, CloudFront retrieves data from the Amazon S3 bucket and distributes it to multiple datacenter locations.

Amazon CloudFront works seamlessly with Amazon Simple Storage Service (S3) to accelerate the delivery of your web content and reduce the load on your origin servers. 


Amazon CloudFront is a web service that speeds up distribution of your static and dynamic web content, such as . html, . css, . js, and image files, to your users.


Benefit of CloudFront?

Great Performance. The AWS CloudFront content delivery network optimizes for low latency and high information transfer speeds. 

CloudFront's intelligent routing predicate on real-world latency measurements incessantly gathered from standard websites, as well as Amazon.com.


Step by step process on getting started in the AWS Console, configuring your origin, and beginning testing your CloudFront distribution:

1. Go to the AWS Console

2. Create an Amazon S3 bucket

3. Create an Amazon CloudFront distribution

4. Specify your distribution settings

5. Configure your origin

6. Configure Origin Access Identity

7. Configure default cache behavior

8. Configure your TTLs

9. Configure additional features

10. Test your CloudFront distribution

Date Time in Laravel and PHP with Carbon

This article covers how to manage date/time easily in Laravel and PHP with Carbon. Basically, Carbon is a package that helps us to deal with date/time in Laravel and PHP in a much easier and systematic manner.

Working with date and time in PHP is not the easiest or most clear of tasks. We have to deal with strtotime, formatting issues, lots of calculations, and more.


Carbon provides some nice functionality to deal with dates in PHP such as:

1. Dealing with timezones

2. Getting current time easily

3. Converting a datetime into something readable

4. Parse an English phrase into datetime (first day of January 2016)

5. Add and Subtract dates (+ 2 weeks, -6 months)

6. Semantic way of dealing with dates


Carbon is already included in Laravel so there's no need to go and add it with Composer.

Whenever we need to use Carbon, we can import it like so:

<?php

use Carbon\Carbon;

After importing you can do a lot with this great package.
