At this point, cloud-based applications aren\u2019t a new concept. Many organizations have shifted from legacy systems to the cloud to build faster applications that better fulfill customer needs and meet their demands. If you\u2019re just beginning your modernization journey, this guide will help you increase your understanding of how to utilize cloud computing to build applications. We\u2019ll go over considerations for app building, provide a step-by-step development guide, and outline all the costs you should be aware of before \u200bselecting a cloud provider. Whether you’re a complete novice or an experienced developer looking for a quick refresh, this blog post will provide the information you need to create secure, scalable applications.<\/span><\/p>\n

What are Cloud-Based Apps?<\/span><\/h2>\n

Before diving into the development process, it’s essential to understand what cloud-based applications are. Cloud-based applications, often called cloud apps, are software programs that operate on remote servers and are accessed through the Internet. Unlike traditional software applications you install on individual devices or local servers, cloud-based apps leverage the infrastructure and resources of cloud computing to deliver services.<\/span><\/p>\n

Types of Cloud Computing<\/span><\/h2>\n

Cloud-based solutions come in various forms, each catering to specific business needs and preferences. The main types of cloud computing are:<\/span><\/p>\n

Public Cloud<\/span><\/h3>\n

Description<\/b>: Public cloud solutions are provided by third parties and are accessible to the public over the Internet. These third-party providers, which include <\/span>Amazon Web Services (AWS)<\/span><\/a>, <\/span>Microsoft Azure<\/span><\/a>, <\/span>Google Cloud Platform (GCP)<\/span><\/a>, and Oracle Cloud Infrastructure (OCI), maintain and manage the underlying infrastructure.<\/span><\/p>\n

Use Cases<\/b>: Public cloud computing is a suitable type for various applications, from web hosting and email services to data storage and machine learning. Startups and small to midsize businesses often favor them due to their cost effectiveness and scalability.<\/span><\/p>\n

Private Cloud<\/span><\/h3>\n

Description<\/b>: Private cloud solutions are dedicated to a single organization and aren\u2019t shared with other entities. They can be hosted on-premises or by a third-party provider. Private clouds offer greater control, security, and customization than public clouds. <\/span>RedHat<\/span><\/a> provides different solutions that can serve all the private cloud functions, like <\/span>OpenStack<\/span><\/a> and <\/span>OpenShift<\/span><\/a>.\u00a0<\/span><\/p>\n

Use Cases<\/b>: Private clouds are ideal for organizations with strict data security and compliance requirements, such as government agencies, healthcare providers, and financial institutions. They\u2019re also good for larger enterprises that must maintain complete control over their infrastructure.<\/span><\/p>\n

Hybrid Cloud<\/span><\/h3>\n

Description<\/b>: Hybrid cloud solutions combine elements of both public and private clouds. This approach allows you to share data and applications between them. Organizations can move workloads between the two environments based on cost, performance, and security.<\/span><\/p>\n

Use Cases<\/b>: Hybrid cloud computing is suitable for businesses with fluctuating workloads or those looking to extend their existing infrastructure to the cloud gradually. This type offers flexibility and data redundancy.<\/span><\/p>\n

Multi-Cloud<\/span><\/h3>\n

Description<\/b>: Multi-cloud strategies involve using multiple public cloud providers simultaneously. This approach helps avoid vendor lock-in, enhance resilience, and leverage the unique strengths of each cloud provider.<\/span><\/p>\n

Use Cases<\/b>: Enterprises often adopt multi-cloud strategies to optimize their cloud services. For example, an organization may use AWS for its machine learning capabilities, Microsoft Azure for its integration with Windows-based systems, and GCP for its data analytics tools.<\/span><\/p>\n

Considerations for Building Cloud-Based Applications<\/span><\/h2>\n

Building cloud apps involves several considerations to ensure your application performs optimally, remains secure, and meets your business objectives. Here are some key development considerations:<\/span><\/p>\n
