AWS Support – The First Decade

We launched AWS Support a full decade ago, with Gold and Silver plans focused on Amazon EC2, Amazon S3, and Amazon SQS. Starting from that initial offering, backed by a small team in Seattle, AWS Support now encompasses thousands of people working from more than 60 locations.

A Quick Look Back
Over the years, that offering has matured and evolved in order to meet the needs of an increasingly diverse base of AWS customers. We aim to support you at every step of your cloud adoption journey, from your initial experiments to the time you deploy mission-critical workloads and applications.

We have worked hard to make our support model helpful and proactive. We do our best to provide you with the tools, alerts, and knowledge that will help you to build systems that are secure, robust, and dependable. Here are some of our most recent efforts toward that goal:

Trusted Advisor S3 Bucket Policy CheckAWS Trusted Advisor provides you with five categories of checks and makes recommendations that are designed to improve security and performance. Earlier this year we announced that the S3 Bucket Permissions Check is now free, and available to all AWS users. If you are signed up for the Business or Professional level of AWS Support, you can also monitor this check (and many others) using Amazon CloudWatch Events. You can use this to monitor and secure your buckets without human intervention.

Personal Health DashboardThis tool provides you with alerts and guidance when AWS is experiencing events that may affect you. You get a personalized view into the performance and availability of the AWS services that underlie your AWS resources. It also generates Amazon CloudWatch Events so that you can initiate automated failover and remediation if necessary.

Well Architected / Cloud Ops Review – We’ve learned a lot about how to architect AWS-powered systems over the years and we want to share everything we know with you! The AWS Well-Architected Framework provide proven, detailed guidance in critical areas including operational excellence, security, reliability, performance efficiency, and cost optimization. You can read the materials online and you can also sign up for the online training course. If you are signed up for Enterprise support, you can also benefit from our Cloud Ops review.

Infrastructure Event Management – If you are launching a new app, kicking off a big migration, or hosting a large-scale event similar to Prime Day, we are ready with guidance and real-time support. Our Infrastructure Event Management team will help you to assess the readiness of your environment and work with you to identify and mitigate risks ahead of time.

Partner-Led Support – The new AWS Solution Provider Program for APN Consulting Partners allows partners to manage, service, support, and bill AWS accounts for end customers.

To learn more about how AWS customers have used AWS support to realize all of the benefits that I noted above, watch these videos (and find more on the Customer Testmonials page):

The Amazon retail site makes heavy use of AWS. You can read my post, Prime Day 2017 – Powered by AWS, to learn more about the process of preparing to sustain a record-setting amount of traffic and to accept a like number of orders.

Wearable clothing gets cool

from Wearable clothing gets cool
by John Weir

The Swiss textile innovator HeiQ launches an upgraded version of its popular dynamic cooling technology HeiQ Smart Temp. Based on an instant cooling hydro functional polymer, this patent pending technology provides activated cooling to the wearer for enhanced performance and thermal comfort. Inhouse thermoregulation performance measurements of a treated fabric revealed a 1.5°C to 2.5°C (2.7°F to 4.5°F) cooler skin temperature compared to an untreated fabric.

The Swiss textile innovator is now offering a new addition to the HeiQ Smart Temp family: HeiQ Adaptive AC-06. This patent pending technology version equips the sports enthusiast with activated cooling and enhanced performance and thermal comfort. Upgraded HeiQ Smart Temp interacts with the wearer, helping to lower the skin’s temperature when it needs it most. The innovation is based on an instant cooling hydro functional polymer that is activated when the skin temperature exceeds a range between 28°C and 32°C (82.4°F and 89.6°F) and deactivated once cooling is complete. Two actions are used to keep the body at the optimum performance temperature: Even before the first sign of sweat on fabric, a melting action is activated, sending instant-cooling impulse directly to the skin. And when the heat is really turned up, a vaporizing action transports sweat away from the body, reducing the skin’s temperature by 1.5°C to 2.5°C (2.7°F to 4.5°F) compared to an untreated fabric sample. Overall, the wearer feels cool, comfortable and focused to perform better – even in the most uncomfortable of conditions.

Inhouse thermoregulation performance testing has revealed high reduction rates of the skin temperature measured over a certain time by utilizing a thermal imaging infrared (FLIR) camera. The FLIR camera set-up imitated the human skin while sweating at different levels of activity. “In contrast to the Dynamic Evaporation testing, the FLIR camera measurement allows us to quickly though accurately visualize the temperature change of a fabric treated with HeiQ Smart Temp, for example compared to an untreated fabric sample,” says HeiQ’s Chief Technology Officer Walter Nassl.

Get Started with Blockchain Using the new AWS Blockchain Templates

Many of today’s discussions around blockchain technology remind me of the classic Shimmer Floor Wax skit. According to Dan Aykroyd, Shimmer is a dessert topping. Gilda Radner claims that it is a floor wax, and Chevy Chase settles the debate and reveals that it actually is both! Some of the people that I talk to see blockchains as the foundation of a new monetary system and a way to facilitate international payments. Others see blockchains as a distributed ledger and immutable data source that can be applied to logistics, supply chain, land registration, crowdfunding, and other use cases. Either way, it is clear that there are a lot of intriguing possibilities and we are working to help our customers use this technology more effectively.

We are launching AWS Blockchain Templates today. These templates will let you launch an Ethereum (either public or private) or Hyperledger Fabric (private) network in a matter of minutes and with just a few clicks. The templates create and configure all of the AWS resources needed to get you going in a robust and scalable fashion.

Launching a Private Ethereum Network
The Ethereum template offers two launch options. The ecs option creates an Amazon ECS cluster within a Virtual Private Cloud (VPC) and launches a set of Docker images in the cluster. The docker-local option also runs within a VPC, and launches the Docker images on EC2 instances. The template supports Ethereum mining, the EthStats and EthExplorer status pages, and a set of nodes that implement and respond to the Ethereum RPC protocol. Both options create and make use of a DynamoDB table for service discovery, along with Application Load Balancers for the status pages.

Here are the AWS Blockchain Templates for Ethereum:

I start by opening the CloudFormation Console in the desired region and clicking Create Stack:

I select Specify an Amazon S3 template URL, enter the URL of the template for the region, and click Next:

I give my stack a name:

Next, I enter the first set of parameters, including the network ID for the genesis block. I’ll stick with the default values for now:

I will also use the default values for the remaining network parameters:

Moving right along, I choose the container orchestration platform (ecs or docker-local, as I explained earlier) and the EC2 instance type for the container nodes:

Next, I choose my VPC and the subnets for the Ethereum network and the Application Load Balancer:

I configure my keypair, EC2 security group, IAM role, and instance profile ARN (full information on the required permissions can be found in the documentation):

The Instance Profile ARN can be found on the summary page for the role:

I confirm that I want to deploy EthStats and EthExplorer, choose the tag and version for the nested CloudFormation templates that are used by this one, and click Next to proceed:

On the next page I specify a tag for the resources that the stack will create, leave the other options as-is, and click Next:

I review all of the parameters and options, acknowledge that the stack might create IAM resources, and click Create to build my network:

The template makes use of three nested templates:

After all of the stacks have been created (mine took about 5 minutes), I can select JeffNet and click the Outputs tab to discover the links to EthStats and EthExplorer:

Here’s my EthStats:

And my EthExplorer:

If I am writing apps that make use of my private network to store and process smart contracts, I would use the EthJsonRpcUrl.

Stay Tuned
My colleagues are eager to get your feedback on these new templates and plan to add new versions of the frameworks as they become available.

Unicorn Light Switch Cover #3DThursday #3DPrinting

Fantasy inspired switch plate shared by nebocreek on Thingiverse:

I’m very new to printing and modelling but I saw the Unicorn light switch cover plate by MikeMasek and thought my girls would go bonkers for it. Only issue was that it wouldn’t fit on my Monoprice Select Mini. So, I hacked this one together and probably made all kinds design mistakes but it worked and the girls love it. If you’d like to tell me all the things that could be improved, I’m all ears and eager to learn.

If you decide to print this on a MP Select Mini, be advised…I changed my print bed x and y dimensions to 127 to make this work. On one pass while printing the raft I did hear it bump against its hard limit so if you can make it work with everything set to 126 mm you might be better off. Needless, this print makes for a very full print bed on the MPSM.

I printed with white PLA and it turned out pretty well. On the next one, I’ll probably increase the outer layer a bit because it is a little translucent in some light. It is also 1 or 2mm smaller in diameter than the cover that was on there but it still covers well and looks good. Last thing is that the screws won’t sit flush unless you dremel them out a bit…could be easily fixed in the model. If I do another version, I’ll fix this in the model.
