Published by Springer. - [Decentralized Cloud Storage Based on Blockchain Networking](/research) · Research · Published research on attribute-based access control, blockchain security events, and untrusted cloud storage. - [Build portable boundaries, not lowest-common-denominator clouds](/notes/build-portable-boundaries-not-lowest-common-denominator-clouds) · Note · Multi cloud strategies often begin with a desire to avoid lock in and end with a platform that hides every useful provider capability. Portability is more effective when it is applied… - [Use the strangler pattern for controlled cloud migration](/notes/use-the-strangler-pattern-for-controlled-cloud-migration) · Note · Large migrations fail when “move the system” is treated as one indivisible project. The strangler pattern reduces risk by placing a controlled boundary around the existing system and… - [Choose Kubernetes tenancy boundaries deliberately](/notes/choose-kubernetes-tenancy-boundaries-deliberately) · Note · Kubernetes can host many teams and workloads, but a namespace is not automatically a complete security, reliability, or cost boundary. Tenancy design should begin with the risks that… - [What is cloud computing?](/notes/what-is-cloud-computing) · Note · Cloud computing is the on demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user.… - [Downtime with Cloud Computing](/notes/downtime-with-cloud-computing) · Note · Downtine in Cloud Computing Cloud Outage simply refers to the duration when the cloud infrastructure service is unavailable for use. The unavailability may also refer to performance… - [High-performance computing in the cloud](/notes/high-performance-computing-in-the-cloud) · Note · HPC stands for High Performance Computing, the name dictattes itslef. This is the vertical in which cloud computing offers extremenly high resources in the computation side. AWS is run… - [Poly-cloud architecture](/notes/poly-cloud-architecture) · Note · A poly cloud is a cloud approach that uses different types of cloud services that are hosted onto various clouds. A poly cloud approach runs different kinds of cloud services on one… - [Multi-cloud architecture](/notes/multi-cloud-architecture) · Note · Multi cloud is the use of two or more cloud computing services from any number of different cloud vendors. A multi cloud environment could be all private, all public or a combination of… - [Distributed cloud](/notes/distributed-cloud) · Note · DISTRIBUTED CLOUD Distributed cloud enables a geographically distributed, centrally managed distribution of public cloud services optimized for performance, compliance, and edge computing. - [Community cloud](/notes/community-cloud) · Note · Community cloud computing refers to a shared cloud computing service environment that is targeted to a limited set of organizations or employees (such as banks or heads of trading… - [Hybrid cloud](/notes/hybrid-cloud) · Note · Hybrid cloud refers to a mixed computing, storage, and services environment made up of on premises infrastructure, private cloud services, and a public cloud—such as Amazon Web Services… - [Private cloud](/notes/private-cloud) · Note · Private cloud is a cloud computing environment dedicated to a single customer. It combines many of the benefits of cloud computing with the security and control of on premises IT… - [Public cloud](/notes/public-cloud) · Note · A public cloud is a type of cloud computing in which a third party service provider makes computing resources—which can include anything from ready to use software applications, to… - [Serverless computing and Function as a Service](/notes/serverless-computing-and-function-as-a-service) · Note · Function as a Service (FaaS) is a serverless way to execute modular pieces of code on the edge. FaaS lets developers write and update a piece of code on the fly, which can then be… - [Mobile Backend as a Service (MBaaS)](/notes/mobile-backend-as-a-service-mbaas) · Note · Mobile backend as a service (MBaaS), also known as "backend as a service", is a model for providing web app and mobile app developers with a way to link their applications to backend… - [Platform as a Service (PaaS)](/notes/platform-as-a-service-paas) · Note · Platform as a service (PaaS) or application platform as a service (aPaaS) or platform based service is a category of cloud computing services that allows customers to provision,… - [Software as a Service (SaaS)](/notes/software-as-a-service-saas) · Note · SaaS stands for software as a service, which means software is hosted by a third party provider and delivered to customers over the internet as a service. While most SaaS products are… - [Infrastructure as a Service (IaaS)](/notes/infrastructure-as-a-service-iaas) · Note · Infrastructure as a service (IaaS) are online services that provide high level APIs used to dereference various low level details of underlying network infrastructure like physical… **Dhruv Doshi** · Toronto, Canada · [work@doshidhruv.com](mailto:work@doshidhruv.com) [Resume](/resume)[Notes](/notes)[Guides](/guides)[Topics](/topics)[Search](/search)[Research](/research)[LinkedIn](https://www.linkedin.com/in/dhruvdoshi25071999)[GitHub](https://github.com/DhruvDoshi) [Sitemap](/sitemap.xml)[RSS](/feed.xml)[LLMs](/llms.txt) © 2026 Dhruv Doshi
