The Challenge

Atom bank, the UK’s first app-based bank, was facing challenges with its existing infrastructure which was slowing growth and limiting the bank’s agility. As the bank attracted more customers and wanted to offer more products, it began to feel the need for a more robust and flexible infrastructure. Initially, due to regulatory constraints, Atom bank had partnered with a third-party to host its infrastructure in an on-premises data center. However, as regulations evolved to accommodate cloud computing, Atom bank began searching for an alternative infrastructure. The bank needed a solution that would ensure speed and reliability even as it gained more customers and added more services. It also needed to be cost-effective and agile, allowing the bank to start new projects or launch new environments without having to invest in new hardware every time.

About The Customer

Atom bank is the UK’s first app-based bank, launched in 2016. It has quickly gained popularity due to its focus on providing a simpler experience for its customers, while offering extremely competitive rates. Atom bank uses technology to cut down on the overheads of more traditional banks and provide a slick, smooth service that you’d get from the best mobile apps. The bank's success is also attributed to its consumer-friendly lending and saving policies. As a “challenger bank”, Atom bank competes against much more established competitors with vast resources, and hence, has to carefully decide how to spend its time, effort, and money on improving the offering.

The Solution

Atom bank chose Google Cloud as its cloud provider for its technical capabilities, level of service, and competitive pricing. The bank began its modernization journey in 2019, planning the project in two phases. The first phase involved moving the network middleware onto the cloud, and the second phase involved redesigning the core banking stack for a microservices-based architecture utilizing a variety of in-house and external systems fit for the cloud. Atom bank moved its digital mortgages website to Google Cloud as a low-stakes way of learning how to work with the new technology. The bank then rebuilt and redesigned much of its stack in the cloud, hiring a team of DevOps engineers and recreating the middleware for the core banking elements on Google Cloud. Atom bank also used Vault, a cloud-native platform designed specifically for banks by Thought Machine, a Google Cloud Premier Partner, for its core banking services. The bank also designed areas such as a new monitoring and notifications system for its infrastructure and redesigned its data architecture.

Operational Impact

  • With Google Cloud, Atom bank was able to build a brand new cloud-based banking stack designed for security, scalability, and a seamless customer experience. The bank was able to increase speed and lower latency on the app, improve customer experience with enhanced infrastructure control, and quickly respond to any technical issues. The bank also developed a culture of enhanced agility. The transition to Google Cloud also allowed Atom bank to bring in changes like real-time data streaming and dramatically improve development times, with same-day production changes. This has made the bank much more agile as an enterprise, and it can focus on the things that really matter for its customers. The bank was also able to launch a brand new Instant Saver account which was well-received by customers.

Quantitative Benefit

  • Cut environments lead time by up to 98%

  • Reduced the time to set up a new development environment from 42 weeks to just one week

  • Improved app store ratings

IoT System for Tunnel Construction
The Zenitaka Corporation ('Zenitaka') has two major business areas: its architectural business focuses on structures such as government buildings, office buildings, and commercial facilities, while its civil engineering business is targeted at structures such as tunnels, bridges and dams. Within these areas, there presented two issues that have always persisted in regard to the construction of mountain tunnels. These issues are 'improving safety" and "reducing energy consumption". Mountain tunnels construction requires a massive amount of electricity. This is because there are many kinds of electrical equipment being used day and night, including construction machinery, construction lighting, and ventilating fan. Despite this, the amount of power consumption is generally not tightly managed. In many cases, the exact amount of power consumption is only ascertained when the bill from the power company becomes available. Sometimes, corporations install demand-monitoring equipment to help curb the maximum power demanded. However, even in these cases, the devices only allow the total volume of power consumption to be ascertained, or they may issue warnings to prevent the contracted volume of power from being exceeded. In order to tackle the issue of reducing power consumption, it was first necessary to obtain an accurate breakdown of how much power was being used in each particular area. In other words, we needed to be able to visualize the amount of power being consumed. Safety, was also not being managed very rigorously. Even now, tunnel construction sites often use a 'name label' system for managing entry into the work site. Specifically, red labels with white reverse sides that bear the workers' names on both sides are displayed at the tunnel work site entrance. The workers themselves then flip the name label to the appropriate side when entering or exiting from the work site to indicate whether or not they are working inside the tunnel at any given time. If a worker forgets to flip his or her name label when entering or exiting from the tunnel, management cannot be performed effectively. In order to tackle the challenges mentioned above, Zenitaka decided to build a system that could improve the safety of tunnel construction as well as reduce the amount of power consumed. In other words, this new system would facilitate a clear picture of which workers were working in each location at the mountain tunnel construction site, as well as which processes were being carried out at those respective locations at any given time. The system would maintain the safety of all workers while also carefully controlling the electrical equipment to reduce unnecessary power consumption. Having decided on the concept, our next concern was whether there existed any kind of robust hardware that would not break down at the construction work site, that could move freely in response to changes in the working environment, and that could accurately detect workers and vehicles using radio frequency identification (RFID). Given that this system would involve many components that were new to Zenitaka, we decided to enlist the cooperation of E.I.Sol Co., Ltd. ('E.I.Sol') as our joint development partner, as they had provided us with a highly practical proposal.

Real-time In-vehicle Monitoring
The telematic solution provides this vital premium-adjusting information. The solution also helps detect and deter vehicle or trailer theft – as soon as a theft occurs, monitoring personnel can alert the appropriate authorities, providing an exact location.“With more and more insurance companies and major fleet operators interested in monitoring driver behaviour on the grounds of road safety, efficient logistics and costs, the market for this type of device and associated e-business services is growing rapidly within Italy and the rest of Europe,” says Franco.“The insurance companies are especially interested in the pay-per-use and pay-as-you-drive applications while other organisations employ the technology for road user charging.”“One million vehicles in Italy currently carry such devices and forecasts indicate that the European market will increase tenfold by 2014.However, for our technology to work effectively, we needed a highly reliable wireless data network to carry the information between the vehicles and monitoring stations.”
