No matter which provider you choose, you'll find that almost every cloud has these core characteristics: It's virtual Imagine racks of servers, humming along in a data center. Together, these servers become a massive pool of resources. Divide this "pool" into multiple virtual servers, and you create a "cloud." It can be secure For the utmost security, create a private cloud on dedicated hardware. But always remember to put appropriate security measures in place, no matter which cloud you choose. It's flexible and scalable Since virtual servers aren't physical, they are super flexible, giving you what you need at the moment. Spin up a server in minutes, and take it down just as easily. It can be affordable You'll get the greatest cost savings in the public cloud, where your virtual servers run on physical servers that you share with other customers. It's open (or closed) In the open cloud, you can easily move your cloud around—without being locked into one provider or a closed, proprietary technology. It can be secure and affordable A hybrid cloud gives you the benefits of both public and private clouds. For example, you can put public-facing components in a public cloud, while storing customer-sensitive data in a private cloud.The “cloud” in cloud computing can be defined as the set of hardware, networks, storage, services, and interfaces that combine to deliver aspects of computing as a service. Cloud services include the delivery of software, infrastructure, and storage over the Internet (either as separate components or a complete platform) based on user demand.Cloud computing has four essential characteristics: elasticity and the ability to scale up and down, self-service provisioning and automatic deprovisioning, application programming interfaces (APIs), billing and metering of service usage in a pay-as-you-go model.The world of the cloud has lots of participants: • The end user who doesn’t have to know anything about the underlying technology. • Business management who needs to take responsibility for the governance of data or services living in a cloud. Cloud service providers must provide a predictable and guaranteed service level and security to all their constituents. •The cloud service provider who is responsible for IT assets and maintenance.•The cloud service provider who is responsible for IT assets and maintenance.Cloud computing can completely change the way companies use technology to service customers, partners, and suppliers. Some businesses, such as Google and Amazon, already have most of their IT resources in the cloud. They have found that it can eliminate many of the complex constraints from the traditional computing environment, including space, time, power, and cost.

The document provides an introduction to cloud computing, defining key concepts such as cloud, cloud computing, deployment models, and service models.

Specific examples of websites that successfully use stories are provided. The presentation encourages designers to think of themselves as modern storytellers and to integrate narrative elements into their design process from the beginning of a project.

The number of microservices running in enterprises increases daily. As a result, service composition, governance, security, and observability are becoming a challenge to implement and incorporate. A “cell-based” architecture is an approach that can be applied to current or desired development and technologies to address these issues. This technology-neutral approach helps cloud-native dev teams become more efficient, act in a more self-organized manner, and speed overall release times. In this deck, Asanka will introduce the "cell-based" architecture, which is decentralized, API-centric, cloud-native and microservices friendly. He will explain the role of APIs in the cell-based approach, as well as examine how real applications are built as cells. Asanka will explore the metrics and approaches that can be used to measure the effectiveness of the architecture and explore how organizations can implement the cell approach.
