Best Public Cloud Storage Services

Public cloud services work under a shared responsibility model. This means the vendor is responsible for the security of the cloud environment and infrastructure as a whole and the user is responsible for the security of their data and workloads. Keeping the data secure in the cloud is critical when opting for a cloud storage service. When looking at cloud service providers, here are some security features to consider:

1. Advanced firewall: Data in the cloud requires extended firewall features like checking the packet content for integrity and stability.
2. Intrusion detection system: Most compliance standards require organizations to track and record intrusion attempts. So IDS event logging is essential for organizations in regulated industries that need to comply with PCI, DSS, or HIPAA regulations. Some cloud providers offer intrusion detection monitoring to detect threats and malicious IP addresses.
3. Application and database firewalls: The perimeter firewall can block external attacks but internal threats exist as well. Cloud storage services that implement internal firewalls to restrict access to databases and applications offer a new layer of protection against internal threats. These can also block an attacker trying to move laterally inside the environment.
4. Encryption at rest and in transit: Data must be protected not only when transferred from or to the cloud but also while at rest inside the cloud storage. This is an effective way to keep sensitive information from an attacker. That way, even if an attacker can steal the data, they cannot use it without knowing the decryption key.

Unlike in the public cloud, in the private cloud, the user does not share the service with any other organization. Their cloud is dedicated to the company only.

Contrarily, in a public cloud, the services are shared by different customers, although each user’s data is hidden from other cloud users. A private cloud can be compared with renting a private house. It is more expensive but more private. A public cloud can be compared to an apartment building. The tenants share the common infrastructure but they each have their own space for their belongings.

Private clouds can be hosted, which means they are offered by a third-party cloud provider, or internal, which means they are managed and maintained by the organization.

Opting for a cloud storage platform has several benefits, like easy access to data and files. When looking for a cloud storage service, there are important features to look for:

1. File versioning: This feature enables you to edit files without fearing the service will overwrite them. Instead, these services keep several versions of your files so you can go back to the old copies later. Most services can even allow you to retrieve a deleted file.

1. Collaboration tools: Easy file sharing with other authorized users is a must to allow for collaboration in distributed workforces. The best cloud storage services also ensure secure access to protect the shared data.

1. Automatic synchronization: This feature updates the files in real time to reflect the edits you make. Automatic syncing saves you from having to sync manually, with the risk of losing data. Some cloud storage services also provide automatic backups so you can rest assured that no data is lost.

1. Security and file encryption: Your cloud storage service should encrypt the data at rest as well as in transit. The best services even allow you to pick the encryption key and identity and access management. Access control lets you ensure only the right user has access to the data.

1. Flexibility and affordability: Pricing models vary according to the platform. Some storage platforms offer limited data and get more expensive when scaling up. Others are more expensive at the outset but get more affordable with time. It is important that the cloud storage feature offers the flexibility to scale up or down in an affordable manner.

Ensuring data security in Public Cloud Storage Services involves implementing strong encryption methods for data at rest and in transit. You should also utilize access control policies to restrict who can access your data. Regular security audits and compliance with industry standards like ISO/IEC 27001 enhance the protection of your sensitive information. Using multi-factor authentication also adds an extra layer of security. It's imperative to continuously monitor and update your security measures according to the latest threats and vulnerabilities.

Cost optimization in Public Cloud Storage involves evaluating your storage needs and selecting the right storage class that matches your usage patterns. Implementing lifecycle management policies can help automate data transfer to lower-cost storage tiers. It's crucial to regularly analyze your billing reports to identify unused or underutilized resources. You may also consider using spot instances or reserved capacity for predictable workloads to reduce costs. Optimizing data storage by removing redundant data and utilizing data compression techniques can further enhance savings.

High availability in Public Cloud Storage can be achieved by leveraging data replication across multiple regions or availability zones. Implementing a robust architecture that includes automatic failover mechanisms ensures consistent data accessibility. You should also utilize load balancing to distribute workloads effectively and maintain optimal performance. Regularly test your disaster recovery plan to ensure it meets your availability requirements. Using redundant network paths and backup strategies significantly contributes to higher availability levels.

Public Cloud Storage offers businesses scalability, enabling you to easily adjust your storage needs. It provides cost-efficiency as you pay only for the storage you use, eliminating the need for investing in physical infrastructure. Accessibility from anywhere with internet connectivity allows you to collaborate more effectively. Advanced security features offered by cloud providers ensure the safety of your data. Additionally, automatic updates and maintenance free up your IT resources to focus on core business functions rather than managing storage infrastructure.

Data migration to Public Cloud Storage involves planning and assessing your current data architecture. Begin by identifying which data needs to be moved and select the appropriate migration tools provided by your cloud service provider. Consider network bandwidth, data size, and transfer time during migration planning. It's crucial to test the migration process to ensure data integrity is maintained. Post-migration, verify that all systems can access the data as required and perform optimally in the new environment. Continuous monitoring can ensure the migration meets your business requirements and goals.
