My experience with AWS Certified Security – Specialty

M

Last week I took the AWS Certified Security – Specialty exam — and I passed with a score of 930 (Woohoo!!) In this post I cover why I took it, what I did to pass, my overall exam experience, and some tips I learnt along the way. So let’s go. Why? Why would anybody pay good money, subject themselves to hours of studying, only to end up sitting in a cold exam room for hours...

Lambda functions in a VPC

L

In my honest (and truly humble) opinion, VPCs don’t make much sense in a serverless architecture — it’s not that they don’t add value, it’s that the value the add isn’t worth the complexity you incur. After all, you can’t log into a lambda function, there are no inward connections allowed. And it isn’t a persistent environment, some functions may...

Using Terraform and Serverless Framework

U

Image from wikicommons. The Serverless framework (SF) is a fantastic tool for testing and deploying lambda functions, but it’s reliance on cloudformation makes it clumsy for infrastructure like DynamoDB, S3 or SQS queues. For example, if your serverless.yml file had 5 lambdas, you’d be able to sls deploy all day long. But add just one S3 bucket, and you’d first have to sls...

IBM vs. AWS the battle of the cloud providers

I

If you’re looking at implementing a large scale cloud offering, something where you measure capacity in chunks of 100TB, then you might want to weigh in on the pros and cons of each possible Cloud provider. Or you could just read 79 page protest Amazon filed in a US court claiming it’s ‘successful’ bid on a CIA tender was legit, and IBM had no business going to the...

Malaysia Data Center aspirations

M

A bernama report a couple of days ago mentioned that Malaysia was ‘well-positioned’ to be a world class preferred hub for data centers: KUALA LUMPUR, April 18 (Bernama) — Malaysia is well-positioned to be a world-class preferred hub as a data center thanks largely to the government’s liberal investment policies, solid infrastructure and a large supply of people with...

Undersea Cables in Malaysia : The Need for infrastructure

U

A good friend and regular reader (or so I hope) of this blog sent me this link last week. It’s a really nifty chart of all the undersea cables in the world. Now, for those who don’t know what undersea cables are, they’re basically the huge data cables that carry around the data we use for the internet. While modern satellites orbit overhead, the unfortunate truth is that...

Cracking Passwords with the Cloud

C

I ┬áremember my computer security professor telling me that encryption doesn’t make it impossible to decrypt, but rather infeasible to decrypt. Nobody is going to buy a supercomputer to crack your final year thesis, simply because the data isn’t worth nearly as much as the cost to crack it–thereby making it infeasible. With cloud computing, however, end-users and regular joes...

MSC Cloud Initiative : Why it’s a bridge too far

M

Why does Amazon–arguably the biggest cloud player in the world–choose to launch it’s Asia-Pacific Offering in Singapore rather than Malaysia? One would think that the prohibitively high prices of land in Singapore, coupled with it’s higher base cost and employee wages would make Singapore a terrible place to put up a Huge Datacenter comprising of thousands of Servers and...

When Lightning strikes the Cloud: Amazon Outage

W

Google recently announced their Amazon EC2 killer, the Google Compute Engine or GCE. Google wasn’t messing around and went straight for the Amazon jugular releasing 4 instance types all of which appear cheaper than their Amazon counterparts. That being said the price comparison was done solely on the basis on a on-demand Amazon instance types–Amazons most expensive prices, if you...
