AWS Outage Prevention: Single Сloud with multi-Region or Multi Сloud?

Cloud .NET Development

Making choices about cloud technology without deep design knowledge or architectural expertise leads to escalating long-term problems, especially for companies that hire low-cost .NET development agencies to save money upfront. This technical debt worsens over time and costs companies three to ten times more to fix than the initial software development. Extremely low-cost .NET developers frequently deliver applications as a single, large unit (monolithic applications) that cannot scale to support growth. This forces clients to completely rebuild the software (re-architecture) soon after release. Vendor lock-in adds further risk: you become overly dependent on a single cloud provider such as AWS, Azure, or GCP. When applications perform poorly, these performance bottlenecks are usually caused by poor application architecture too. To avoid these risks, companies should work with development firms that can demonstrate specialized expertise in cloud-native architecture.

Multi-Tenant SaaS Identity and Access Control Management

SaaS platforms have different customers/subscribers, or, “tenant” users, in technical terms. For B2B SaaS such tenants are often organizations. If the SaaS platform is deployed in the cloud using multitenant architecture for cost-effectiveness, the platform’s customers use the same databases and storages as others. SaaS platform owners have to prevent user access from one customer to another customer's private information. The solution is the implementation of multi-tenant SaaS identity and access control management.

What is IaaS (Infrastructure-as-a-Service)?

Infrastructure-as-a-service (IaaS) is a cloud computing service from a cloud service provider where you receive access to compute, storage, and networking resources on-demand and are charged for what you use. Additional services include billing management, logging, monitoring, storage resiliency, and security. In this model, the IaaS provider maintains the physical infrastructure, so you can concentrate on the development of your core business software. Businesses use the IaaS to migrate some or all of their use of on-premises or collocated data center infrastructure to the public, private, or hybrid clouds to become more agile, and innovate faster.
