Your laptop counts. You will, after all…it’s a computer. But some of our planet’s computing power is now being implemented in so-called “edge” computing areas, in remote devices such as sensors and other smart devices.
Not necessarily synonymous with the Internet of Things (IoT), edge computing happens on the IoT devices themselves, hence the need for a separate term and validation. Some of the edge computing happens on large, advanced devices from hospital equipment to digital instrumentation installations in oil and gas facilities – and some of it just happens on your smartphone. The common thread linking the two scenarios here is that neither of them necessarily have to have a link to a cloud data center, i.e. the computations and calculations have to happen locally on the hardware in the first place, and then everything is on the edge.
But, despite its inherent remoteness, how do we test edge computing and make sure our (often smaller) smart devices are doing what they’re supposed to be doing?
Paramount Focus – The Podium
for ntt Param sanduIt is down to many factors, but it is able to identify a number of key trends and practices. In his role as Vice President, Enterprise 5G Products and Services at NTT Ltd, Sandhu says the governance, monitoring and management of the underlying hybrid computing platform used along with the deployed application layer are of paramount importance. Today, there is a widespread trend for software tools at this layer to attempt to provide an automated “glass pane” for managing multi-tiered, hyper-cloud hybrid environments as well as edge computing ownership.
“Enterprise mission-critical applications require guaranteed performance of Service Level Agreements (SLAs) from the underlying edge computing platform. Enterprise technology managers require demonstrable capabilities that ensure that the underlying edge platform can meet application performance requirements before they can confidently move mission-critical applications to ( Or in a situation where it is integrated with) a high-end computing platform,” NTT’s Sandu said.
He explains that performance-guaranteed SLAs can only be delivered when the correct operating system and hardware schema methodology is used in the design and deployment phases. Then, the cloud management software used must also be able to demonstrate that the specified SLA is achievable and achieved during the RUN phase when the edge hardware is running.
The imitation stage is much needed
NTT Joseph May He agrees with his colleague’s ideas. In his role as NTT’s Vice President of Solution Architecture, he also feels that one of the biggest challenges in the field comes when a company is looking to test and validate its cutting-edge software, and a staging (or certification) environment is often lacking. . This is a computing environment that simulates what will eventually be a live “production” environment as closely as possible.
But why is it so difficult to imitate a real production environment?
“Even if you can get a backup of the data from already experienced real-world data archives that have passed (and through) the edge computing layer, it’s still difficult to re-run the data ingestion workload in the same pattern as the data traffic,” specified May. “This is because data is usually ingested from many data sources…and the data produced from all of those data sources is dependent on many ‘initial’ events.” [a multiplicity of potential actions of machines, databases and users that occurs prior to the edge device needing to do its job].
There’s a lot of focus here on precision engineering at the data level, so why is it all so important? A lot of the reasons come down to the fact that when it comes to edge implementation (which is latency sensitive, time sensitive, and is in a multiple input multiple output system), some issues only arise when the sequence of events follow a certain path, under a certain timing.
Temporary fixes become fixtures
“This means that no matter how much testing is done, some production defects can still be missed during the quality assurance stage,” May explained. Furthermore, if a production defect is discovered, the engineer may not be able to recreate the exact same defect to uncover the root cause. If the root cause cannot be found, the next best alternative is to apply a temporary fix, which will live in the system forever.”
But edge computing and the Internet of Things aren’t the only parts of our universe where temporary fixes become sticky. As an example that is not connected randomly, the Egyptian capital is interconnected with “BridgeThe overpasses, some (local opinion says) were designed to be only temporary, still stand today.
Back in the world of edge computing, we can see that sometimes, the cost of creating complex simulations to comprehensively test a device or service is actually prohibitive. The consensus here is that we should do temporary repairs as minimal as possible, that is, they deteriorate and wear out over time.
What is the future of our edge?
If we’ve come this far then, how should we look at the edge-enabled future of IoT? Edge computing used to be dominated by discrete “point” solutions from a single company — and back then, things were almost simpler, May and the NTT team advise.
“Today, an end-to-end end-to-end computing solution consists of components from multiple vendors. Add to that the fact that solutions are getting more and more complex with multiple vendors using products and services in the mix… and you can see we have a lot to manage. Then think about the need Consider confidentiality, IP ownership, liability and you have another complex layer of hurdles on top of an already technically complex solution,” May advised.
The broader trends found here point to a tightening of technology policy.
Sometimes it is now being imposed and managed through the policy-as-code approach As we explained herewe are moving into the realm of the IoT edge where IT governance must require a company (and indeed the high-end hardware supplier that provides this business) to comply with certain policies.
For example, summed up by NTT’s Mai, all edge application modules can be run in an environment where they have to be deployable to containers and thus can be managed by certain edge application manager technologies – a new formal approach to computing that we can already see in capital letters EAM. If we can build our own smart edge systems with some (or all and more) of these elements, maybe we can test them better, run them better, and (when they go wrong) sort out errors with shorter average time to resolve (MTTR) numbers.
As we build the Internet of Things with the power of edge computing, these devices — or at least the central computing engine in them — are often smaller machines as independent pieces of technology, but making them work efficiently is a big job.
