Major Concerns to Build the Public Cloud

Security & Compliance

Where cloud-computing is one of the best ways to gear up for business success, simultaneously, it is the responsibility of both the customer and public cloud service provider to maintain and manage a secure IT environment. Both sides must play their role in maintaining the security of the cloud to ensure that the data is safe and well-protected. And for this reason, it is referred to as shared responsibility environment.

Shared Responsibility Environment

It ensures optimum customer/user security and data safety, providing its services in a highly-secured and a controlled platform. It offers a wide range of security features that customers can use for their data protection. On the other hand, the customer’s role is to configure their IT environment in a controlled and secure manner.

The shared responsibility environment typically to relieve users’ from operational burden. It manages, operates as well as controls all components from the host OS (operating system) while the user/customer takes on the responsibility and management of the guest OS which includes updates & security patches. The customer also takes full responsibility of the associated application software programs and configuration provided security-group firewall.

Additionally, it also gives customers the flexibility to enhance their security to meet their compliance and industry specific certification requirements. This can be done by leveraging technologies like host-based intrusion detection & prevention, key management and encryption and host-based firewalls.

Multi-Tiered Cloud Security Standard for Singapore (MTCS) Compliance

The world’s first cloud security standard, The Multi-Tier Cloud Security (MTCS), covers multiple tiers of cloud security that can be adopted by Cloud Service Providers (CSPs) to meet different cloud user needs for data sensitivity and business criticality.

The IDA evaluates the security practices of cloud service providers in their cloud environments to ensure that it complies with the requirements for multi-tiered cloud computing security in order to be certified as a MTCS Cloud Services Provider.

Cloud services focuses on strong compliance governance and requires all customers/users to maintain proper and adequate governance over their entire IT control environment. Some of the leading practices are to:

  • Develop a strong understanding of compliance objectives
  • Establish a controlled environment that meets these objectives
  • Develop a strong understanding of the validation required based on the customer’s risk tolerance.

Data Migration to Cloud

If you’re thinking to switch to the cloud, then you might be worried about data loss during migration. When switching to the cloud, safe and secure data migration is the biggest challenge for businesses as the risk is high. However, the best way to ensure safe and secure data migration to cloud is to first develop your data migration strategy.

You will first need to determine the best approach based on the dynamics and specifics of your IT environment. Here, it is important to understand that there are several ways to migrate data from your business premises to the cloud.

Some of the most popular strategies to lift and shift data to the cloud include:

  • Onetime large batches
  • Intermittent updates
  • Constant device streams
  • Hybrid data storage strategy

These data migration strategies can be used both separately and together to help successfully switch to the cloud.

Whether to combine different data migration strategies or not, depends on factors like:

  • How much data has to be migrated?
  • How long will it take to transfer data over the existing web connection?


Though data migration is a concern and a challenge, customers don’t typically worry about this as MTCS Certified Cloud Services Provider takes security in the cloud very seriously and offers excellent and several security features in all of its services.

Network Connectivity

Cloud Service Provider helps to establish a fast, well-structured and dedicated network connection. This is created between the customer’s network and at the cloud location. It can be easily divided or partitioned into several virtual interfaces enabling you to use the same network connection to smoothly access public resources like objects that are stored.

This is done by using public Internet Provider’s address space and private resources. Virtual interfaces can also be reconfigured at any time to successfully meet the changing business needs and on-going demands.

Let’s take a deeper dive to understand the benefits that network connectivity offers to users:

Lowers the cost of Bandwidth

It can significantly lower your network cost in case you have bandwidth heavy workloads and want to run in the cloud. Wondering how? Well, firstly, since the data is transferred directly, it reduces your bandwidth commitment to your ISP (Internet Service Provider). And secondly, all data that is transferred over the cloud network connection is charged, that too, at the reduced data migration rate instead of internet data transfer rate.

The customer gets to select the data that uses the dedicated network connection and also how the data is routed. This helps provide users a more consistent experience as compared to internet based connections.

Scalability at Your Fingertips

With cloud network connectivity, you can easily scale your connection to meet your on-going business needs. It offers one Gbps and ten Gbps connections. In case, if you need more capacity, you can also provision several new connections.


Auto-scaling helps to maintain application availability at all times. Auto-scaling helps resize the capacity up and down automatically. It’s the perfect way to ensure that you’re running your cloud to its full potential.

When the demand spikes, auto-scaling automatically increases the capacity. This helps maintain performance. On the other hand, during lulls, the auto scaling feature lowers capacity, helping you to keep cost low. This product is perfect for both applications that experience variability and that have consistent demand patterns.

Here is a closer look at some of the amazing benefits of the auto-scaling feature:

  • Quick Detection and Replacement 
    Auto-scaling can be a great product to invest in as it helps getting you the compute capacity that you, the user, expects. The auto-scaling feature is smart enough to detect and identify impaired instances as well as unhealthy applications. Wait there’s more! Not only does it automatically identify problematic instances but it also immediately replaces them, sparing you from the hassle and stress.
  • Automatically Scales
    With auto-scaling, you can easily meet your business demands as it helps you follow the changing demand curve for your application meticulously. It practically eliminates the need to manually provision capacity. All you need to do to ensure that it is scaled timely when needed is to pre-set conditions to add new instances and remove instances. If you can predict load changes, you can also then set a proper schedule through auto-scaling and define your scaling activities in advance.
