Amazon Web Services (AWS), is a collection of remote computing services, also called web services, that make up a cloud-computing platform  operated from 11 geographical regions across the world. The most central and well-known of these services include Amazon Elastic Compute Cloud, also known as "EC2", and Amazon Simple Storage Service, also known as "S3". Other services include Elastic MapReduce (EMR), Route 53 (a DNS web service),  provides a highly available and scalable Domain Name System (DNS) web service, Virtual Private Cloud (VPC), storage, database, deployment and application services.

Is this the end of IT management tools?
Or at least that’s the word according to a new blog from Tech Target on AWS’s new Managed Services (MS) offering. According to the blog, AWS is launching their AWS MS program to expedite the adoption of cloud by Fortune 1000 and Global 2000 companies. The article published last week notes AWS’ belief that companies want:
 

[T]o add additional automation, make use of standard components that can be used more than once, and to relieve their staff of as many routine operational duties as possible.


Further explanation is provided in AWS’ announcement of their new product which they claim is designed to take over system monitoring, incident management, change control provisioning and patch management. Indeed, these are usually functions that fall under the auspices of IT Ops. And as the Tech Target article goes on to note:


After all of this, the only ones left standing could be application developers, despite — or thanks to — Amazon’s vast array of development tools.


So, if we follow AWS’s logic, we might think that they have sunk their claws into the whole IT management life-cycle. The question then becomes, has AWS set the stakes for IT management to meet its maker? Ummmm, not so fast, Cowboy.


One cloud to rule them all

If you are thinking of adopting cloud services, or just curious as to what ‘the cloud’ can offer then the leader according to Gartner for Infrastructure as a Service (IaaS) is Amazon Web Services (AWS).  When I started using AWS I was completely new to the offering and I really didn’t know what it was, how it worked or what to do once I had access.  This article will cover some of the main points to be aware of that may help you when you first start out using the Services they provide.
 
The 1st thing you will want to do is to create an account, AWS offer you the ability to use some of their services for free for a year as long as it falls within their specific ‘free tier’ limits.  I used my own personal account for self study and learning and I found these service limits to be perfectly fine for what I wanted to do and test.  By default you will have access to ALL services that they provide, and you will only be charged for any services that you use that fall outside of the initial free tier.
 
The complete service limitations on what the free tier offers can be found here.  The main services that feature within this and the most common that you will initially use are:
 
Compute (EC2)
  • 750 hours worth of EC2 Compute Capacity for RHEL, Linux or SLES t2.micro instances
  • 750 hours worth of EC2 Compute Capacity for Windows t2.micro instances
As an example, you could run a single Windows instance constantly for 1 month, or 2 Windows instances for half a month, etc.

Glacier Costs
AWS Glacier is Amazons cheapest storage option and is their answer to a ‘Cold’ storage service.  Customers primarily use this service for archival purposes and storage of infrastructure backups.  Its unlimited storage potential and low storage cost makes it a popular storage choice.
 
What can be sometimes overlooked are the retrieval costs of your data, depending on how much you retrieve and over what time period can make a huge difference.  This article will cover these costs and help you understand the considerations of data retrieval.  Its important to note that AWS prices are exclusive of any GST or VAT chargeable (more information on these fees can be found here.)
 
Retrieval Costs
 
When you find yourself in a situation where you need to retrieve data from Glacier you need to understand some of the costs to ensure you can complete it in the most cost effective way. 
 
You will probably be aware that AWS boasts a retrieval rate of $0.01 per GB; however this is not as simple to calculate as it seems.
 
It’s important to note that you can retrieve up to 5% of your total AWS Glacier for free each month which is monitored on a pro rata basis daily.  Therefore if for example you have 15TB of data stored on Glacier you could retrieve 25GB a day for free (15TB * 5% (0.05) / 30(days) = 25GB).  25GB would be your daily free allowance.
 
Any data retrieved over this amount per day will be chargeable based upon other …

Security is one of the biggest concerns when moving and migrating your data from your on-premise location to the Public Cloud.  Where is your data? Who can access it? Will it be safe from accidental deletion?  All of these questions and more are important, and AWS knows and addresses this. 
 
Due to AWS being a global company deploying exactly the same services in all corners of the globe it has had to set the highest level of security conforming to all regulations in each country.  As a result, someone who is simply using S3 to store their personal photos gets the same level of security as a multi million dollar company who require the most vigorous of security regulations.
 
AWS complies with a number of different security standards that can be found here.
 
When it comes to Security, AWS operates within a shared responsibility model.  This means that the security ‘of’ the Cloud lies with AWS, and the security ‘in’ the cloud lays with you the user.  To break this down a bit further, the physical access to the Data Centres, Availability Zones, Regions, Edge Locations, Compute, Networking and Storage is the responsibility of AWS.  Your data and its encryption, configuration of your VPC security covering ACLs, Security Groups, IAM, patching of EC2 instances etc, is your responsibility. 
 
More information on the Shared model can be found here.

Review of Cloudberry Explorer Pro - Linked with Amazon Web Services (AWS) S3


Being a Cloud technology fan and in particular services that are provided by AWS, I was interested to find a growing number of vendors writing software and applications that claim to blend and mesh with AWS services providing enhanced functionality and a better user experience. 

One of these vendors within this industry are Cloudberry Lab, who are an Advanced Technology Partner with AWS.  Looking into their products further I could see they heavily centred their solutions on Backup and Storage integration with a number of cloud providers.  I was specifically interested in their products that aligned with the AWS S3 Service.
Following an overview of their range of products I decided to download Cloudberry Explorer Pro for S3.  It claimed that Explorer for Amazon S3 provides a user interface to Amazon S3 accounts allowing to access, move and manage files across your local storage and S3 buckets”.  It also boasted a number of additional features, many of which are listed below:

Picture1.pngSome of these I would find more useful than others, but I ultimately wanted to see how this software would change my experience of using S3 from my local PC perspective when moving and transferring data into and out of S3.  I was keen to use the features such as the Compare and Sync …

With the spotlight very much on Cloud technology within the IT industry, it’s difficult to avoid the topic these days. Due to the constant flood of new information, added pressure, emphasis and focus on cloud migration is driving corporations to investigate and understand what ‘the cloud’ actually is and discuss if they should utilise this technology as a potential gain to their business. 
 
As this understanding and knowledge of the Cloud grows, many Senior Directors and CTOs are taking a different look at their own infrastructure estate with one question hanging over their heads: Should we consider migrating some/all of our services to the Cloud? 

This article is your guide when asking that very same question.
 
There are many pieces to consider and some of them will be more applicable to others depending on your line of business, your company size, and your strategy. However, all items should be considered before making a decision to ensure you have sufficient information to deliver a successful Cloud infrastructure environment for you and your customers.

Here are the questions to ask yourself when deciding whether or not to migrate to the cloud:
 

1. Do you need the Cloud?

 
The first question you should ask yourself is “Do I need the cloud?”  Before answering this question you need to have an understanding of what the Cloud can provide you and your business, its features and benefits, its potential gains, and its risks and restrictions. You …

AWS has developed and created its highly available global infrastructure allowing users to deploy and manage their estates all across the world through the use of the following geographical components
 
  • Regions
  • Availability Zones
  • Edge Locations
 
When architecting and designing your infrastructure it’s important to know where your data is being stored and where your instances and services are located.  This is fundamental when designing and implementing a highly available and scalable network with low latency that abides by any data laws that may be in operation.
 
If you are studying for the AWS certifications it’s important to know the differences between Regions/Availability Zones and Edge Locations.
 

What is an AWS Region?

 
A Region is essentially just that, a geographic location that Amazon has selected to run and operate its Cloud services from.  There are currently 12 different regions exist spanning across the globe at key locations:
 
North American Regions
  • US East (Northern Virginia)
  • US West (Northern California)
  • US West (Oregon)
  • AWS GovCloud (US) – Reserved for Government agencies only
South American Regions
  • São Paulo
EMEA Regions
  • EU (Ireland)
  • EU (Frankfurt)
Asia Pacific Regions
  • Asia Pacific (Singapore)
  • Asia Pacific (Tokyo)
  • Asia Pacific (Sydney)
  • Asia Pacific (Seoul)
  • China (Beijing) – Limited Public release

Hi Prathap,

Thank you for your comment.  

Edge location are different from Regions, and as a result do not fall under 'Regions' as a location.  To put the global infrastructure in it's most simple form the different elements can be described as follows:

- Availability Zones (AZs): These are essentially the physical data centers of AWS. This is where the actual compute, storage, network, and database resources are hosted

- Regions: A Region is a collection of availability zones that are geographically located close to one other. This is generally indicated by AZs within the same city.  Regions do not include Edge Locations, only AZs

- Edge Locations: These are AWS sites deployed in major cities and highly populated areas across the globe and they far outnumber the number of availability zones available.  These are used to reduce latency to end users by using the AWS CDN service known as CloudFront.  You are unable to deploy your typical compute, storage, and database services in Edge Locations, the Edge Locations are reserved for simply reducing latency using CloudFront and Lambda@Edge services.

I hope this helps.

Cheers,

When using AWS as your chosen public cloud provider you will ultimately come to a point where you need to decide and define what your storage requirements are for your data that you wish to store on AWS. There are a variety of options to choose from depending on your needs, each with different attributes ranging from: temporary storage, permanent storage, highly available object based storage and even cold archival storage.

This article has been written to give you a high level overview, hopefully containing enough information to guide you in selecting the most appropriate storage service you require. Additional information has been provided for each option with links to offici al AWS documentation.

The remainder of this article will be broken down in to the following sections:
 
  • Defining you Storage Needs
  • AWS Storage Services
  • Moving Data into AWS
  • Costing
 

Defining your Storage needs


To understand what you need from your storage solution you need to understand and ascertain what elements are important to the data being stored. You need to ask yourself the following questions to help and guide you to the correct service/solution for your storage.
 
  • How critical is this data?
  • How sensitive is the data you need to store?
  • How often will the data be accessed?
  • How large is the data?
  • Who requires access to the data?
  • How much are you prepared to pay for to store the data?
  • Where is your data coming from?

Hello to you all,

I hear of many people congratulate AWS (Amazon Web Services) on how easy it is to spin up and create new EC2 (Elastic Compute Cloud) instances, but then fail and struggle to connect to them using simple tools such as SSH (Secure Shell) and RDP (Remote Desktop Protocol) and their feelings quickly turn to frustration. 

Depending on your deployment method of your EC2 instances you may need to connect to them to perform additional configuration, install applications or to troubleshoot and incidents that may occur.  Without having a working method of connecting locally to your EC2 instances would prevent you from having full manageability of that host.

This Article has been written to cover the most common configuration problems that prevent connectivity between you and your EC2 instance.
 

Default or Non Default VPC (Virtual Private Cloud)?


Default VPC: Every AWS account comes with a Default VPC already created, this allows users to immediately deploy EC2 instances within this VPC and connect to it.  Simple you may think, and you would be right, many of the AWS networking components have already been set up on your behalf allowing you to connect to your instances with relative ease. However, these same components that are pre-configured take away some of the detailed design that your corporate infrastructure may require.  It comes with a predefined IP CIDR (Classless Inter-Domain Routing) block assigned which might not suit …

For many, many years, I have been a pessimist in supporting the migration of my applications to the cloud. I had spent the last 25 years of my career running data centers of my own where my staff and I would architect, design, buy, build and run hundreds of systems to support the company’s business. At one point in the late 90’s, I was running more than 8000 servers across multiple data centers with an annual run-rate in the millions of dollars.

Why was I a pessimist you ask? Well, it was always the standard cliché that you read about in any study. I felt I could do a better job than one of those “big” companies at managing my own environments and the amount of redundancy, availability and monitoring I needed wasn’t available at the time. I had also felt that I had perfected the “speed to market” issues by having a small quota of spare equipment ready for a quick start-up if needed along with standard images setup to boot.
 
About four years ago, I started consulting for companies. I was hit head on with the cloud issue as many of my customers wanted to migrate to the cloud as they needed to reduce their costs and overhead of having data center floor space, assets on the books and large IT staff and tools to manage it. I was forced to begin trying it out, having to take crash courses on the differences between IaaS, PaaS, SaaS, private cloud, public cloud, etc. Oh, I had implemented virtualization with VMware and other products to maximize the efficiency in the hardware …

The cloud may be ready in technical means, but I don’t think the countries are ready for it.
Some financial crisis in the latest years have proven that no company, no matter its size, is immune.
Such a company can disappear a year from now for example, leaving its customers without their data.
There's no doubt that cloud computing has changed the way we behave with data, but such a major change
should come with laws.
In the absence of such laws, can we really feel protected with cloud computing ?
If my data is gone and my customers can't receive service, will I be protected from lawsuits.
If my financial data is gone and I'm required by law to submit data to the authorities based on them, will they care if I tell them that my cloud hosting company disappeared ?
Will governments take control of data and facilities of such cloud hosting companies in case of such a disaster, and protect the data ?
I guess the answer is - who knows...
So technically, yes, the cloud is ready for anything. But unfortunately I don't think that's enough.

I maintain it should be a tool in the toolbox.  There are instances and circumstances where it's not practical to go 100% cloud... I do think with the offerings that exist and what most businesses do, EVERY business is likely to benefit from moving SOME operations to the cloud... but all?  No.  What depends on who you are, where you are, what you do, and how you work best.
