[Draft Approval Comment]
1. Summary: "minimum two independent public cloud platforms": the cited source says so but this is not a common definition or criterion. Check other sources as well. 2. Example in the first question is still not clear. Cited references are about multicloud solutions from AWS and Azure. They don't actually explain multicloud. Hence, those citations are not correct for this answer. Answer needs to be corrected. 3. Multicloud vs polycloud: needs to be better. Error: "The key difference is that multicloud ... whereas multicloud and hybrid cloud". "Polycloud is a general term": not exactly. In fact, it's more specific than multicloud. Polycloud implies specialization. 4. References: add publication dates, cite peer-reviewed technical journals.

1. Summary:
- "a single cloud platform": citation is needed. I could be an integration of multiple cloud platforms. My own comment from first review perhaps misled you. I am not an expert. That's why research is important and citations must be given.
- "minimum two independent public cloud platforms": the cited source says so but this is not a common definition or criterion. Check other sources as well.
2. Good first question and example but its the explanation for polycloud not multicloud! So, this answer is wrong for multicloud. You need to get a good understanding of multicloud vs polycloud. See https://www.oreilly.com/library/view/what-is-polycloud/9781098104634/ch01.html and https://www.thoughtworks.com/insights/blog/cloud/multicloud-for-enterprises
3. Benefits: image is about cloud management in general and not specific to multicloud. Find a better image. Image is actually good but doesn't belong in this article.
4. Hybrid cloud: okay. Multicloud vs polycloud: needs to be better.
5. Use case: hard to read. Content looks okay though. Perhaps organize it better into shorter paragraphs.
6. References:
- no publication dates given for any source, although many sources have shared the dates.
- Wikipedia: say "Wikipedia", not "Contributors".
- Research could have been better: there's not a single reference from peer-reviewed technical journals.

1. Summary:
- Image is fine
- Definition is wrong: "Multicloud is the combination of multiple cloud computing and storage services." Here multiple is a generic word. A single cloud platform provides multiple cloud resources and services.
- "increase cloud infrastructure capabilities and cost": increased cost?
- "an structured strategy": grammar error.
- Not good to mention private or on-premise when defining multicloud. It can be mentioned in discussion after introducing hybrid cloud. A multicloud using some on-premise resources is sometimes called hybrid multicloud. Don't take my work on this unless you find a good source for it.
- Overall, summary can be improved for the average developer.
2. A new question as the first question: can give a concrete example to explain multicloud.
3. Benefits:
- Explanation is somewhat verbose. Can make it concise. Perhaps if bullet points are converted into paragraphs and summarized, it will read better.
- This question is repeated later. All benefits to be combined into a single answer.
- The use of the image is unclear. Doesn't seem to relate to multicloud. Seems more about cloud management in general.
4. Use cases: these are also really benefits rather than use cases. However, we can keep this question since the ideas are presented differently.
5. Variations:
- Intercloud is not clear. A example might help here.
- Polycloud is an important specialization to cover.
- Some sources to improve this answer: https://www.cloudflare.com/learning/cloud/multicloud-vs-hybrid-cloud/ , https://www.oreilly.com/library/view/what-is-polycloud/9781098104634/ch01.html and https://www.infoworld.com/article/3655089/managing-the-complexity-of-cloud-strategies.html
6. Editorial:
- "And, make the most of those resources.": rewrite for formal communication.
- "So, ": can be written in a better way.
- We don't encourage creating headings in answers. Content has to be a paragraph or a bulleted list where applicable. This comment is applicable to all answers where headings are used.
7. Security monitoring: too specific a sub-topic: I think this will be a separate article. Can remove it from this article. Moreover, the answer is specifically about MUSA and doesn't cover many other aspects of security monitoring.
8. Milestones:
- 2011: Hybrid cloud is fine. Other milestones of 2011 are not relevant to multicloud. IBM SmartCloud framework: is this a multicloud framework? If so, it needs more contextual info.
- 2012: Oracle: similar to previous comment. We need only those milestones specific to multicloud.
- This is a recent and evolving field. From 2012 till now, many important milestones ought to be available.
9. Benefits and challenges are well-written. Otherwise, the article needs much more work. Only more quality research can reveal how this article can be improved.

Single cloud vs Multicloud. Source: Synoptek

Multicloud (multi-cloud or multi cloud) is a cloud computing strategy. It involves utilizing multiple cloud platforms and services from different vendors within a single IT architecture. The primary purpose of this approach is to enhance cloud infrastructure capabilities, increase flexibility, and optimize costs. Multicloud describes how cloud resources, such as software, applications, and data, are distributed across various cloud hosting environments, which may include public, private, or hybrid clouds..

Multicloud combines two or more cloud platforms. The mulicloud architecture usually has minimum two independent public cloud platforms. These platforms are either public or private.

Multicloud deployment has various benefits. For example, using multiple IaaS, PaaS, and SaaS vendors, including different cloud vendors for different services, excess and system backup.

Discussion

How can we understand multicloud with an example?
Let's understand multicloud with an example:
Imagine a medium-sized e-commerce company, "TechMart," that wants to leverage cloud computing to enhance its online store and customer experience. To achieve their goals, they decide to adopt a multicloud strategy. Here's how they use multicloud:
Web Application Hosting: TechMart chooses to host its web application on AWS (Amazon Web Services) due to its robust and scalable infrastructure. AWS provides excellent support for web hosting, allowing TechMart to handle fluctuating traffic during peak shopping seasons efficiently.
Data Storage and Analytics: TechMart deals with a large volume of customer and transaction data. To optimize data storage costs and performance, they decide to use Microsoft Azure's cloud data services. Azure offers a wide range of data storage options and advanced analytics tools that suit their needs.
Email and Communication Services: For seamless email communication with customers and employees, TechMart selects Google Cloud Platform (GCP) for its reliable and feature-rich email services.
Disaster Recovery: To ensure business continuity and data redundancy, TechMart also maintains a private cloud in their on-premises data center. This private cloud acts as a disaster recovery environment, replicating critical data from the public cloud providers.

A multicloud approach gives multiple options to a company. Some advantages of multicloud are:
Stakeholders can choose the most effective solution. They can distribute resources among cloud providers. They need to pay only for their usage based on business needs. Enterprises gain better computing resources and higher cloud security. They have reduced outages and vendor lock-in risks. SLAs between various service providers secure customers from failures or downtime. Multicloud aids enterprises to optimize service, price, and resources. It also improves data security and interaction flexibly.
Multicloud allows selecting suitable components and cloud services. they can be selected from various vendors based on business needs. It is based on factors like cost, performance, security, compliance, and location preferences. It provides quick adoption of new technologies from any vendor. Businesses need a strong strategy and governance framework for a successful multicloud implementation.
What is the difference between multicloud, hybrid cloud and polycloud?

Multicloud refers to the practice of using services and resources from more than one cloud companies. In a multicloud setup, an company would possibly use one cloud provider for positive workloads or packages and every other cloud issuer for exclusive tasks. The intention is to leverage the strengths of every cloud issuer even as avoiding supplier lock-in and ensuring redundancy.
Hybrid cloud, uses both on-premises hardware and cloud hosting. It could lead to a shift to a public cloud. A hybrid cloud lets businesses connect their existing infrastructure. And also, the employees' skill sets to a more cloud-centered future.
Polycloud is a general term that encompasses any cloud computing infrastructure that uses multiple clouds. It can be public, private, or hybrid. This term includes both multicloud and hybrid cloud environments. The key difference is that multicloud does not specify the exact combination of clouds used, whereas multicloud and hybrid cloud are more specific about their configurations
What are the some of the use cases for multicloud?
Businesses use a variety of cloud platforms and services. This helps with their digital transformation.
Companies are choosing to deploy apps on public, private, and edge clouds. This best serves their business goals and application requirements. Cloud Smart has taken the position of Cloud First.
Data backup and storage are dependable. They are simpler and less expensive. Concerns about cloud spending, data control, vendor dependence, and lock-in are increasing. Hence, businesses will keep spreading their estate across various surroundings.
Applications need to be closer to physical objects and users. So, they need to be deployed to the edge. This improves automation, efficiency, and consumer experiences. The sectors include logistics, retail, and manufacturing.
The hybrid workforce problem is growing. It's challenging to secure, manage, and enable workers, and their devices. So that, they can be productive everywhre.
What type of challenges can occur in case of multicloud?
IT businesses are adopting multicloud environments. The challenges in achieving their objectives are becoming more visible as:
Different workflow and management tools can be expensive. They can cause excess storage and more infrastructure-complexity. Operating multiple clouds requires expertise. They need more time and human resources. Vendors may employ various strategies or tactics to manage challenges. So, simple processes like providing resource become complicated. They have unique portals, APIs, and processes. They need to be controlled.
A company would be more exposed to potential threats and weaknesses. Thus, more work is required for effective security, governance, and consent. Businesses keep introducing new multi-platform tools. Hence, IT leaders need to retrain workers frequently. Companies struggle to recruit employees with the necessary multicloud expertise. It's challenging to adapt quickly to new innovations. The provider maturity levels and API, vary. Multicloud can make these tasks challenging.

Milestones

2011

The hybrid cloud concept is introduced. It requires an interaction between a private and public cloud. It needs the ability to shift workloads between the two clouds.

2012

Multicloud appears when businesses begin to use SaaS providers. These include human resources, customer relations management, and supply chain management.

2013

Multi-cloud trend starts gaining popularity.

2018

The analyst firm Forrester conducts a survey on behalf of Virtustream. It includes cloud strategy and application management decision makers in the US, EMEA, and APAC. The majority of them characterize their organizations' cloud strategy as "multicloud." There are 727 respondents to the survey. 86% of them use multiple public and private clouds for different application workloads.
