Crafted from a mix of open and closed-source software, DDC was first glimpsed in June last year and has been in beta for a while now. It was created after corporate programmers started using Docker containers to package apps with libraries and other dependencies on their laptops, and sysadmins wanted centralized tools to push this code live in a reliable and scalable manner.DDC basically sticks casters on containerized apps and rolls them off coders' laptops, across the factory floor, and out into the sunlight for customers to prod and poke. Docker calls this an end-to-end lifecycle of development, but where's the fun in that?At the heart of the thing is the Docker Trusted Registry, which lets admins manage and store Docker images. Software stacks are then built from these images, tested and deployed using Docker-supplied tools. Images can be cryptographically signed off by developers so that only trusted images end up on production systems.DDC also includes the Docker Universal Control Plane – a key ingredient and the bit that has technically hit general availability today – and, of course, Docker Engine.Below is an overview of the architecture: programmers build and test their images on their dev machines, then push them to the grey blob which is the Docker Trusted Registry, where files are organized and access is strictly controlled. Then images are deployed to on-premises or cloud-based systems as required. If anything it encourages developers to break up their monolithic enterprise applications into separate components that all the cool kids are calling microservices. A new or updated logging microservice can be created by a developer, tested, and pushed to the registry as a Docker image, and then rolled out live as a container for apps to seamlessly use when ops is happy with the change.We've seen our customers take changes that require months to complete, and reduce their deployment to hours, Scott Johnston, Docker's senior veep of product management, told El Reg.For example, the ING bank in Europe would take nine months to deploy a change: it would have to go through all the steps of code review, Q&A, load testing, and staging and so on.With a monolithic application, changing just one line is so fraught with risk. After going in all with microservices, changes can be pushed without having to do a full recompile and rebuild: you can go from nine months to hours.That means customer-facing apps can be rapidly updated with features and tweaks to compete with rivals, for example. It means you can respond to customer requests and competitive pressures, added Johnston. A CIO or CTO can go to the CEO, and say: Hey, these apps we're queuing up? We're delivering them in weeks not months. Docker to date isn't about mind-blowing computer-science breakthroughs; it's all about taking existing technologies that have been cranky to configure and a pain to master, and making them super-easy and smooth to use. Now it's taking that approach to container deployment for enterprises. Microservices isn't for everyone – you can't wave a magic wand and turn all dependencies into separate services, and it can introduce really irritating complexities. Still, a lot of people swear by them.Below is a simplified diagram showing how ADP, a major payroll processing service in the US, has used DDC to switch from monolithic programs to apps that are made up of interchangeable and updatable microservices. It was pretty essential to Docker that it get its software right for ADP, because the finance biz processes Docker staffers' wage slips. Docker uses ADP, so we have an interest in deploying this successfully, said Johnston.As part of our initiative to modernize our business-critical applications to microservices, ADP has been investigating solutions that would enable our developers to leverage a central library of IT-vetted and secured core services that they could rapidly iterate on,” said ADP CTO Keith Fulton.
With Docker, we will be able to ensure application portability, whether it is between dev and ops or between the data center and the cloud.DDC isn't reliant on any particular Linux distribution nor underlying hardware: your kernel and processor just need to support all the low-level stuff that Docker containers are built on. Pricing is based on how many nodes you want to scale DDC on: it's basically $150 per node per month, but do drop them a line to find out more on that score, if DDC floats your container boat. A UK court has approved for the first time the use of predictive coding as a basis for determining which electronic documents are relevant to a dispute.The High Court in London sanctioned its use in a multi-million pound dispute where more than 3 million electronic documents have to be assessed to determine whether they are relevant and disclosable.Master Matthews, who gave the judgment, said the use of predictive coding in the case would promote the overriding objective of the Civil Procedure Rules, which is that courts should seek to deal with cases justly and at proportionate cost. He said, though, that whether it would be right for approval to be given in other cases will, of course, depend upon the particular circumstances obtaining in them. Litigation law expert Michael Fletcher of Pinsent Masons, the law firm behind Out-Law.com, welcomed the decision and said that, if anything, it is surprising it has taken so long for an English court to sanction the use of predictive coding as a means for meeting electronic disclosure requirements.This may be a vision of the future, but also a rather belated approval of the tools that tech-savvy litigators already have at their disposal and have been using to assess cases and in arbitration, Fletcher said. I don't therefore see this ruling as opening the floodgates for predictive coding, as cases will need to be of a certain value and have sufficient quantities of electronic documents to make it viable. However, it may encourage parties to consider predictive coding in High Court standard disclosure exercises going forward.Predictive coding is the use of software to review the majority of electronic documents in a disclosure exercise, instead of human beings. The software is programmed to account for findings made by senior lawyers who have reviewed a sample of the documents; those lawyers 'train' the document review platform as to what documents are likely to be relevant. Having been 'trained', the software then analyses the remaining documents and identifies their relevance to issues in the case,. The senior reviewers subsequently review further samples as a quality control process, determining whether the software has correctly identified relevant documents. This process will iteratively improve the quality of the 'training' until an acceptable level of accuracy is reached..
Fletcher said predictive coding can potentially save businesses involved in litigation both money and time in major e-disclosure reviews, and perhaps even be considered more reliable than manual document review.Master Matthews cited a number of reasons why he was persuaded to sanction the use of predictive coding in the case before him. He said that predictive coding had been shown to be useful in appropriate cases in other jurisdictions already. He referenced cases in the US and Ireland where predictive coding had been used for e-disclosure purposes.The Master said there is no evidence to show that the use of predictive coding software leads to less accurate disclosure being given than, say, manual review alone or keyword searches and manual review combined.Predictive coding will offer greater consistency in applying an approach to document review defined through senior lawyer sampling, rather than would be the case with many junior lawyers or paralegals independently applying the relevant criteria in relation to individual documents, Master Matthews said.The Master also said the English civil procedure rules do not prohibit the use of predictive coding software. He found that its use in this case was merited in part because of the huge number of electronic documents which must be considered for relevance and possible disclosure in the case before him and because it would be far less expensive to use predictive coding software than to proceed with manual searching of documents in the case. The cost of using predictive coding software was deemed to be proportionate to the value of the claims at stake in the wider litigation, the judge said. He said that there is plenty of time to consider other disclosure methods if for any reason the predictive software route turned out to be unsatisfactory in the case before him because the trial in the case is not scheduled until June 2017. The final factor weighing in favour of using the tool was that all the parties in the case had agreed on using the software and the way it is to be used. Michael Fletcher notes that this highlights the benefits that can result from parties collaborating early on disclosure and seeking to find common ground on how to proceed in a cost-effective but robust way.MWC16 Just ahead of Mobile World Congress in Barcelona, Alcatel has announced the Idol 4 and 4S smartphones, complete with VR headset in the box, and a Windows 10 2-in-1 tablet/laptop.Alcatel, formerly known as Alcatel OneTouch, is a brand of the China-based TCL Communications. At a press event in Barcelona, the company unveiled a new logo and announced that it is dropping OneTouch from the name. Specialising in the budget and mid-tier segment, the company claims to be the fiftth largest handset manufacturer in the world, and aims to become number 5 in smartphones and tablets by the end of 2016.
