How to decommission a data center

About the only thing harder than building a data center is dismantling one, because the potential for disruption of business is much greater when shutting down a data center than constructing one.The recent decommissioning of the Titan supercomputer at the Oak Ridge National Laboratory (ORNL) reveals just how complicated the process can be. More than 40 people were involved with the project, including staff from ORNL, supercomputer manufacturer Cray, and external subcontractors. Electricians were required to safely shut down the 9 megawatt-capacity system, and Cray staff was on hand to disassemble and recycle Titan’s electronics and its metal components and cabinets. A separate crew handled the cooling system. In the end, 350 tons of equipment and 10,800 pounds of refrigerant were removed from the site.To read this article in full, please click here

Video: The Need for Network Layers

After identifying some of the challenges every network solution must address (part 1, part 2, part 3) we tried to tackle an interesting question: “how do you implement this whole spaghetti mess in a somewhat-reliable and structured way?”

The Roman Empire had an answer more than 2000 years ago: divide-and-conquer (aka “eating the elephant one bite at a time”). These days we call it layering and abstractions.

In the Need for Network Layers video I listed all the challenges we have to address, and then described how you could group them in meaningful modules (called networking layers).

Even more amazing papers at VLDB 2019 (that I didn’t have space to cover yet)

We’ve been covering papers from VLDB 2019 for the last three weeks, and next week it will be time to mix things up again. There were so many interesting papers at the conference this year though that I haven’t been able to cover nearly as many as I would like. So today’s post is a short summary of things that caught my eye that I haven’t covered so far. A few of these might make it onto The Morning Paper in weeks to come, you never know!

Industry papers

  • Tunable consistency in MongoDB. MongoDB is an important database, and this paper explains the tunable (per-operation) consistency models that MongoDB provides and how they are implemented under the covers. I really do want to cover this one at some point, along with Implementation of cluster-wide logical clock and causal consistency in MongoDB from SIGMOD 2019.
  • We hear a lot from Google and Microsoft about their cloud platforms, but not quite so much from the other key industry players. So it’s great to see some papers from Alibaba and Tencent here. AliGraph covers Alibaba’s distributed graph engine supporting the development of new GNN applications. Their dataset has about 7B edges… Meanwhile, AnalyticDB Continue reading

New in Docker Hub: Personal Access Tokens

The Docker Hub access token list view.
The Hub token list view.

On the heels of our recent update on image tag details, the Docker Hub team is excited to share the availability of personal access tokens (PATs) as an alternative way to authenticate into Docker Hub.

Already available as part of Docker Trusted Registry, personal access tokens can now be used as a substitute for your password in Docker Hub, especially for integrating your Hub account with other tools. You’ll be able to leverage these tokens for authenticating your Hub account from the Docker CLI – either from Docker Desktop or Docker Engine: 

docker login --username <username>

When you’re prompted for a password, enter your token instead.

The advantage of using tokens is the ability to create and manage multiple tokens at once so you can generate different tokens for each integration – and revoke them independently at any time.

Create and Manage Personal Access Tokens in Docker Hub 

Personal access tokens are created and managed in your Account Settings.

From here, you can:

  • Create new access tokens
  • Modify existing tokens
  • Delete access tokens

Note that the actual token is only shown once, at the time Continue reading

Backup the data in AWS Elastic Block Store

A recent Amazon outage resulted in a small number of customers losing production data stored in their accounts. This, of course, led to typical anti-cloud comments that follows such events. The reality is that these customers data loss had nothing to do with cloud and everything to do with them not understanding the storage they were using and backing it up.Over Labor Day weekend there was a power outage in one of the availability zones in the AWS US-East-1 region.  Backup generators came on, but quickly failed for unknown reasons. Customers’ Elastic Block Store (EBS) data is replicated among multiple servers, but the outage affected multiple servers. While the bulk of data stored in EBS was fine or was able to be easily recovered after outage, .5 percent of the data could not be recovered. Customers among the .5 percent who did not have a backup of their EBS data actually lost data.To read this article in full, please click here

IoT Privacy for Policymakers: Solutions Need Informed Discussion

The consumer Internet of Things market is growing exponentially – one prediction suggests that people will be using 25 billion connected devices by 2021. These new products promise innovation and convenience, but they can also erode privacy boundaries and expose consumers to risk without their knowledge or consent. Is that a good bargain?

The policy brief “IoT Privacy for Policymakers” explores this question and more.

Do consumers have enough information and choice to make meaningful decisions? Do vendors and service providers have the opportunity and incentive to bring privacy-enhancing innovations to the market? Can the downsides of IoT be mitigated through policy actions – and if so, how?

“IoT Privacy for Policymakers” explains the scope and nature of IoT privacy and the issues it raises. As ever, those issues are multi-party. They cross the boundaries of jurisdictions and sectoral regulations. There are no single-stakeholder solutions, so a multistakeholder approach is needed. Solutions need informed discussion that includes consumer rights, economic incentives, technical options, and regulatory measures. This paper is a positive step in that direction.

The policy brief also includes a “how to” on implementing Privacy by Design and four Guiding Principles and Recommendations:

BrandPost: A Network for All Edges: Why SD-WAN, SDP, and the Application Edge Must Converge in the Cloud

The software-defined movement keeps marching on. Software-defined WAN (SD-WAN) is redefining the branch edge by displacing legacy technologies like MPLS, WAN optimizers, and routers. Software-defined Perimeter (SDP) is displacing whole network access via mobile VPN with secure and optimized access from any device to specific applications in physical and cloud datacenters. These seem like unrelated developments, despite the “software-defined” buzz, because enterprise IT thinks about physical locations, mobile users, and applications separately. Each enterprise edge, location, person, or application is usually served by different technologies and often by different teams.To read this article in full, please click here
