All the cloud service providers have their own pros and cons. Their make themselves a suitable choice for different purposes. Here, the advantages and disadvantages are described for all the providers. Table 1.2 provides a comparative study on this.

Table 1.1 Comparison between AWS Outpost, Microsoft Azure Stack, and Google Cloud Anthos.

AWS Outpost	Microsoft Azure Stack	Google Cloud Anthos
Amazon has a huge tool set and that too is rapidly growing. No service providers can match with it. But the pricing is bit puzzling. Though providing service for hybrid or public cloud is not amazon’s primary focus thus incorporation of cloud services with on-premise data is not in top priority [20]. They primarily focus on public cloud.	The customer can run in their own data center. Azure tries to incorporate with that. It provides the facility of hybrid cloud [19]. A customer can replicate his environment in Azure Stack. This is very useful in case of backup disaster and for cutting cost.	Google has come to the cloud market later. So, it does not have that much level of focus to incorporate the customers. But the strength is its technical efficiency. Some of its efficient tools are applicable in data analytics, machine learning, and deep learning.
