Sentinel-2 Cloud-Optimized GeoTIFFs Now Available on AWS Registry of Open Data
This week, in collaboration with Geoscience Australia, we released our Sentinel-2 Cloud-Optimized GeoTIFF (COG) dataset on AWS Open Data. Our collection contains all 11.4 million scenes from the Sentinel-2 Public Dataset, except the JPEG2000 (JP2K) files are all converted to COGs. Our dataset is continuously updated to mirror the growth of the public Sentinel-2 data…

AWS Public Safety and Disaster Response Competency
Hanging just above the reception desk at our office in Alexandria are three framed posters–one for each of our company values. Now you may think that’s a bit cheesy–in a sort of team-rowing-motivational poster kind of way–but they truly drive our work, decision making and business outlook at Element 84. For me, our most important…

IAM What IAM And That’s All That IAM
Testing Your IAM Policies As the complexity of your AWS environment grows, the need for more specific Identity and Access Management (IAM) roles, and policies increases. These IAM policies govern not only the users that are logging in to the AWS environment, but also the permissions that are granted to services, Lambda functions, EC2 instances, and…

Serverless Devise with Jets
Over the past few years, serverless design has taken the cloud community by storm. It is hard to ignore–with promises like “pay only for what you use”, “no security patching”, and “infinite scalability”. Being on the cutting edge can have drawbacks too, which in this case is what I would describe as an absence of…

Rising From The Ashes, Untangling the Mysteries of DevOps
There are many books that have influenced me as a software engineer. From the computer science textbooks I used in college, to the animal covered books from O’Reilly I used to pick up new languages and tools, to the Clean Code books from Uncle Bob Martin that helped shape the way I approach software development. However,…

Cloud-native Apps Force Developers to Put Security First

These events justifiably alarm consumers. Every incident cements distrust toward the tech industry, causing technology users to demand better security from software creators.…

Exploring Serverless Portability
With Functions as a Service (FaaS), cloud providers promise us the ability to deploy, run, and scale small pieces of application code without worrying about the underlying hardware or virtual machines. This comes with certain advantages, such as a pricing model that only charges for the amount of time the code is running, quick deployments,…

Fast, Secure, Reliable Uploads to Amazon Web Services from a Web Browser
The Problem Recently, I needed to implement large file uploads to Amazon Web Services (AWS) from a web browser. We had some requirements with possible solutions: S3 is the ideal place to upload files but there are issues with uploading from a web browser to S3. You don’t want to give users free reign to…
