Cloud and Edge are part of the same Continuum

Posted by Marc-Elian Bégin on 10-Oct-2018 11:23:00

There have been wild predictions recently that the edge will overtake if not kill the cloud in terms of volume of data processed. While it is helpful to raise awareness of the potential of edge computing, which is undoubtedly huge, it is also an oversimplification. Instead of adding fuel to this dispute, I prefer to offer peace and bring those two fundamental building blocks together.

How to Map a Billion Stars

Posted by Louise Merifield on 24-Apr-2018 15:57:45

Waiting for Gaia's second data release

Gaia is an ambitious mission of the European Space Agency which will make the largest and most precise 3-D map of our Galaxy by surveying about one billion stars. Which sounds like an awful lot of stars, but amounts to only 1 per cent of the Galaxy's stellar population. The Gaia spacecraft was launched on 19 December 2013 and the mission is planned to continue for 5 years, continually collecting data on the motion and characteristics of stars. The Gaia spacecraft is controlled from the European Space Operations Centre in Darmstadt, Germany.

Improving Emergency Situation Management in Smart Cities

Managing the Fog

Fog computing and edge computing are ways of bringing cloud computing capabilities to the edge of the network and closer to the rapidly growing number of connected devices and sensors that consume computing services and generate massive amounts of data. This raises difficulties in terms of the architecture and management of computing systems and it is exactly this issue which is being addressed by  the mF2C project.

Demystifying Hyperconvergence

Posted by Marc-Elian Bégin on 20-Sep-2016 15:39:29

It's hard to keep up with IT trends. Hyperconvergence is one of the latest buzz words in IT and cloud computing. It embodies an attempt to simplify IT systems and provides simpler hardware and software solutions from which to build integrated cloud services.  It's not surprising, since the IT world is swimming in complexity and most C-level executives are trying to understand why they don't reap the benefit of recent moves toward cloud computing and software-defined everything.

How to Improve Security to Amazon Web Services

Posted by Lionel Schaub on 06-May-2016 12:34:19

Using AWS's security best practices with SlipStream

A little while ago, Amazon Web Services introduced a free service called IAM, which stands for Identity and Access Management. IAM is a great tool which allows you to increase security without too much effort. With it, you can securely control access to AWS services by creating sub-users and retaining a fine grain control over which actions each sub-user can do. You can disable or delete access and secret keys of your AWS root account and create IAM users with the principle of least privilege in mind.

SlipStream is SixSq's multi-cloud application management platform, in other words a launch pad for your apps. It supports a long list of clouds, including AWS, and gives users a simple, quick way to deploy their apps to the cloud of their choice.



SlipStream is inherently secure and provides a simple way for you to launch your apps. You simply create an account via Nuvla, enable AWS, if that's the cloud provider you want, by configuring your account, and off you go. If you are the only one using the AWS account, you're done. If not, you may want to use IAM to create a series of sub-accounts so that you can restrict access to certain parts of your AWS account. To do this, carry out the following actions using IAM.

Enable actions for SlipStream

The following list explains which actions need to be enabled for different features of SlipStream.


Common:

ec2:CreateTags
ec2:ImportKeyPair
ec2:DeleteKeyPair
ec2:DescribeInstances
ec2:RunInstances
ec2:TerminateInstances
ec2:DescribeRegions
ec2:DescribeSecurityGroups
ec2:CreateSecurityGroup
ec2:AuthorizeSecurityGroupIngress

 


For build image:
ec2:CreateImage
ec2:CreateKeyPair
ec2:StopInstances
ec2:DescribeImages

Adding a IAM user for SlipStream

First of all you need to login to the Amazon AWS console at https://console.aws.amazon.com.

Once you are logged in you can access the IAM console by clicking on your name (at the top right) and
then click on `Security Credentials` or you can simply access this URL https://console.aws.amazon.com/iam/.

Now click on `Users` in the left menu and click on `Create New Users`. Set one or more usernames (e.g. SlipStream), make sure the checkbox `Generate an access key for each user` and click on  `Create`.


Then click on `Show User Security Credentials` and save them on a safe place. It will be impossible to retreive the `Secret Access Key` afterwards. You can also click on `Download Credentials` to download them as a CSV file. Please ensure they are stored in a safe place. Click on `Close` to return to the list of IAM users.

Then click on `Policiesers` in the left menu and click on `Create Policy`. Select `Create Your Own Policy`. Set a name for this policy (e.g. SlipStreamUser-Policy) and a description (e.g. Grant the least privileges needed to use all features of SlipStream. Use it for all IAM users created to be used with SlipStream). You can then copy-paste the following Policy Document:


{
"Version": "2012-10-17",
"Statement": [{
"Sid": "SlipStreamUser",
"Effect": "Allow",
"Action": [
"ec2:CreateImage",
"ec2:CreateKeyPair",
"ec2:CreateTags",
"ec2:DeleteKeyPair",
"ec2:DescribeImages",
"ec2:DescribeInstances",
"ec2:DescribeRegions",
"ec2:ImportKeyPair",
"ec2:RunInstances",
"ec2:StopInstances",
"ec2:TerminateInstances",
"ec2:DescribeSecurityGroups",
"ec2:CreateSecurityGroup",
"ec2:AuthorizeSecurityGroupIngress"
],
"Resource": ["*"]}]}


Once this is done you can click on `Create Policy` and you will return to the list of Policies. Now click on the policy you've just created and select the tab `Attached Entities`. By clicking on the `Attach` button, you can select the users for which you want this policy to apply.

Now you can configure your SlipStream user account(s) to use the credentials downloaded previously.
Don’t forget to delete/disable all Access keys of your AWS root account.

What is a Smart City?

Posted by Louise Merifield on 14-Apr-2016 09:00:00

This basic guide to smart cities gives an introduction to one of today's hot topics.

Why is everyone talking about smart cities?

It is estimated that the world’s population will grow to nine billion by 2043 and ten billion by 2083.

This population growth is likely to produce the biggest strain on urban areas, with 11% of the global population currently living in the world’s 101 larger cities - a figure which is expected to rise to 23% by the end of the century. City governers and industry leaders have to find ways to deal with this huge expansion.

At the same time, the latest technological advances give us access to solutions and services which were previously unimaginable. Look at how the internet and smart phone have changed the way you live. To address the key challenges of population expansion and rapid urbanisation, cities are exploring these technological advancements, to find ways to increase efficiency and help tackle the issues that come with an increased population.

My previous post on cloud technologies didn't cover the type of computing resources provided by the cloud or who the customers of cloud services are. Providing those specifics involves understanding some of the jargon associated with the cloud.
