said 65 per cent of outages are in retail banks. She said the regulator received 853 notifications of outages in 2018/19 “that is a huge increase on the previous year”. However, she added some of those incidents were relatively minor, with part of the increase being due to a change in regulatory reporting requirements.

Link: Why are large companies so difficult to rescue (regarding bad internal technology)

In terms of the best integration architecture, what seems to me the only long-term solution is something like the unified log architecture that Jay Kreps wrote about back in 2013. All incoming writes need to go into a centralized log, such as Kafka, and then from there the various databases can pull what they need, with each team making its own decisions about what it needs from that central log. However, SuperRentalCorp has retail outlets with POS (point of sale) systems which talk directly to specific databases, and the path of that write (straight from the POS to the database) is hardcoded in ways that will be difficult to change, so it will be a few years before the company can have a single write-point. For now, each database team needs to be accepting writes from multiple sources. But a unified log is the way to go in the long-term. And that represents a large change of process for every one of those 20 teams. Which helps explain why the company has spent 2 years and $25 million trying to build an API, and so far they have failed.

Link: What’s Hot In Insurance Tech In 2019?

The business backbone, the core systems, burden digital transformation strategies. Insurers spend about two-thirds of finite tech budgets on these run-the-business systems. More nimble competitors are spending more on digital tech. And this run-the-business spend is growing. Tech leaders need to demonstrate business value of these maintenance and ops investments. Benjamin Clarke, the CTO of Bold Penguin, argued that “the project mentality of insurance companies leads to them not building anything interesting but just replatforming again, delivering the exact same experience.”

Link: Assessing IBM i’s Role In Digital Transformation

Making the financial case:

“This is going to sound silly,” he says. “The hardest part isn’t necessarily the refactoring. The hardest part is convincing people to do this. Because, let’s be honest the upfront cost can be very scary, man. It can be frightening. The business is going to say, ‘We just put in X amount of dollars last year to support these kinds of environments.’ You kind of have to ask the question, what’s going to happen five years from now?”

While the legacy application may not be “broken,” forward-looking companies will consider the lost opportunity costs that are inherent when an existing system is not agile enough to support new opportunities and initiatives.

“You’re going to have to have the conversation where you can’t integrate with cloud at all, or you can’t integrate with data analytics, or you’ve failed to do cognitive system and your competitors are because RPG can’t support this stuff?” Kleyman says. “But just because it’s working doesn’t mean necessarily it’s bringing value back to the business.”

It’s easy for an executive to identify problems when servers are down, the application is throwing errors, and the day-to-day business is being impacted. It’s much harder for the executive to be able to identify the ways in which a legacy system could put hamper growth in the future.

“Honestly that’s one of the best approaches, when things aren’t on fire, to start asking some of these difficult questions,” Kleyman says. “It’s kind of like in a relationships. When everything’s going great, you don’t want to bring up any sore points. But realistically speaking, you don’t want to start arguing when everything’s wrong and you start bring up the pain points.”

On the top layer there is rapid change. On the bottom, change happens at a glacial pace. It’s this combination of everything, from seconds at the top, to millennia at the bottom, that give resilience to the system.

And:

A key concept to this is that each layer has to respect the pace of another.

Link: Oracle plans to end Java serialization, but that’s not the end of the story

‘Oracle’s chief architect, Mark Reinhold, shared his thoughts about Java’s serialization mechanism which he called a “horrible mistake” and a virtually endless source of security vulnerabilities. This is evident in nearly half of the vulnerabilities that have been patched in the JDK in the last 2 years are related to serialization. Serialization security issues have also plagued almost every software vendor including Apache, Oracle, Pivotal, Cisco, McAfee, HP, Adobe, VMWare, Samsung, and others.’

Link: Toxic Technology: the growing legacy threat

“The UK Government Digital Service recently wrote about how they understand legacy and suggested a number of factors that contribute to technology being considered legacy: being poorly supported, hard to update, poorly documented, non-compliant or inefficient. The range of breadth of these negative characteristics runs counter to an often passive view of legacy: stable historic technology that is intended to be replaced. Organisations should begin to think of this technology as toxic: actively harmful to the health of the organisation.”

“The CMS platform is used by organizations to manage enterprise applications. Those applications include offerings from SAP and Oracle. CMS includes security, disaster recovery, automated infrastructure, and application management…. IBM launched its Cloud Private service last November. It’s built on a Kubernetes-based container architecture that supports integration and portability of workloads between the cloud environment and management across multiple clouds. This includes IBM Cloud, IBM PowerVC, Amazon Web Services (AWS), Microsoft Azure, and VMware on and off premises.”

Defining and dealing with legacy IT, from a UK government perspective:

“Most organisations have an overarching IT strategy in line with their business strategy but some are taking an alternate approach to legacy. A common tactic is to migrate the business away from legacy in small parts, rather than all at once.”

Link: Serverless at Bustle

‘Probably the biggest is: how do you deal with the migration of legacy things? At Bustle we ended up mostly re-architecting our entire platform around serverless, and so that’s one option, but certainly not available to everybody. But even then, the first time we launched a serverless service, we brought down all of our Redis instances — because Lambda spun up all these containers and we hit connection limits that you would never expect to hit in a normal app.

‘So if you’ve got something sitting on a mainframe somewhere that is used to only having 20 connections and then you moved over some upstream service to Lambda and suddenly it has 10,000 connections instead of 20. You’ve got a problem. If you’ve bought into service-oriented architecture as a whole over the last four or five years, then you might have a better time, because you can say “Well, all these things do is talk to each other via an API, so we can replace a single service with serverless functions.”’

HPE Software sold for $8.8bn, to Micro Focus

While HPE is getting $2.5bn in cash, the whole deal value is more like $8.8bn, the non-cash being stock. More details:

The Numbers

  • “Under the deal, HP Enterprise shareholders are expected to end up with Micro Focus shares currently valued at about $6.3 billion. Micro Focus will pay HP Enterprise $2.5 billion in cash.” (WSJ)
  • There’s about 12,000 people in HPE Software. (WSJ)
  • HPE Software revenue: “HPE’s software unit generated $3.6 billion in net revenue in 2015, down from $3.9 billion in 2014.”
  • Put another way, from TBR: “2Q16 software revenue [had a] decline of 18% year-to-year, driven down by a license revenue decline of 28% year-to-year.”
  • HPE has been divesting a lot, getting a hoard of cash: “In earlier transactions, HP Enterprise in May completed a $2.3 billion deal in China to sell a 51% stake in a venture there called H3C that sells networking, server and storage hardware and related services. Later the same month, HP Enterprise announced a deal to spin off a computer services business that employs about 100,000 people—two-thirds of the company’s total head count—and merge it with operations of Computer Sciences Corp.”
  • Also: “The company sold at least 84 percent of its 60.5 percent stake in Indian IT services provider Mphasis Ltd to Blackstone Group for $1.1 billion in April.”

What now for HPE?
