Hava's AWS Security Views

Posted by Team Hava on August 2, 2018

AWS security groups act as a virtual firewall for your EC2 instances to control inbound and outbound traffic.

"Security groups act at the instance level, not the subnet level. Therefore, each instance in a subnet in your VPC could be assigned to a different set of security groups." -  AWS Documentation

Trawling through your VPC flow logs helps provide visibility into your network traffic to detect anomalous traffic and provides insights, however, it still comes with its own risk of error.

Generating a visual diagram from the source of truth with automated layouts to display your network infrastructure as it is right now can eliminate the potential risk of human error.

Hava offers several ways to assist with diagnosing security within your network.

Still manually updating your network diagrams?

Posted by Team Hava on June 14, 2018

There is no doubt that as we continue to move further into cloud networking and infrastructure our environments are evolving daily. This rapid pace of change is failing to keep up with the expectation that your team knows "how it works" and "what it looks like". Keeping network diagrams up to date is often the last thing on most engineers mind, until the time you need them which in some cases is too late.

Manual creation and updating of diagrams are tedious and time-consuming and not that effective with continuous change. These days we have the ability to automate the process of generating and drawing a diagram, getting the information straight from the source of truth.

5 Tips for Onboarding Cloud Consultants

Posted by Rebecca Rumble on July 5, 2016

So you’ve got approval to hire a consultant on a six-month contract to fast track your project. You’ve found the perfect consultancy with proven success in everything you need to implement. Your Scope of Work (SOW) has been signed off on and your consultant starts in a week. Hoorah!

You want the project to be a resounding success, right?

Onboarding your cloud consultant properly is the most critical thing to you can do to maximize your ROI. They have limited time to deliver you results, not being prepared means your consultant sits idle, and that costs you money.

Design for failure lessons learnt from the Sydney AWS outage

Posted by Rebecca Rumble on June 6, 2016

Sydney’s wild weather brought down an availability zone in AWS’s AP-SOUTHEAST-2 Region on Sunday night.

Websites went down, customer service calls went up, twitter went nuts, engineers scrambled to find work arounds and management started asking “Why?”. 

If your website crashed, you know by now that it’s probably because your application wasn’t designed for region failure.

One outage should not be reason for you to start thinking that the cloud isn’t right for you, or that you should move service providers. But it should make you revisit your architecture. 

Failure in cloud services is inevitable regardless of your provider. Outages happen so you must design for failure. Your actual infrastructure availability is irrelevant to your application availability. 100% uptime should be achievable even when your cloud provider has an outage regardless of its size.

Hava + AWS Summit Sydney 2016

AWS Summit extended to two days for the first time this year and the turn out was amazing! Summit really is the place to be for anyone interested in Amazon Web Services and cloud infrastructure in general.
 
Team Hava was given a space at the AWS Startup Hub and the response to Hava was HUGE! So far beyond our expectations. We got to talk to so many great people with various levels of experience with the cloud - all loving the visibility of their AWS infrastructure Hava will give them. Many couldn't believe we're only one year old!

How confident are you with your cloud infrastructure?

How are you currently creating your cloud diagrams? Are you spending quality time with your whiteboard hand drawing them? Or are you trolling through your AWS console, then clicking and dragging in a drawing tool?

Imagine being able to extract real-time diagrams of your actual AWS environments. That would be pretty cool, right?

Well that’s exactly what Hava does!

Are you monitoring everything?

Posted by Peter Gatt on March 21, 2016

With DevOps now firmly placed in the enterprise sights, we are seeing that automation visibility is becoming critical. Having the view of the state of the delivery pipeline ensures there is an increased awareness of the system as a whole. The question that often arises is “Yes, we need monitoring, but what do we monitor?” There are numbers components of your environments that you should be monitoring, and this blog explores what they are, and why it’s important to monitor them.
