About 10 years ago, the question “Why migrate to Amazon Web Services?” often referred to as “a satire” or “a joke”. Why? Will this question still be satirical in 2021 and beyond? Let’s discuss with VTI Cloud!
Components of an IT system
Since the concept of cloud computing (cloud computing) has been active since 2008-2012, almost all online services when operating will be installed on physical servers (servers), those servers will handle browser requests if you use the web on your computer, then the mobile apps. Websites with a large number of users need to build a database server to store data.
Later modern systems also have additional caching mechanisms to reduce server load and reduce data load times, and then have processing streams for analysis, machine learning, and artificial intelligence applications. create (AI). Each of the components listed above in the system is called a service (service), but companies often have dozens to hundreds of such services, all installed on one or more physical servers.
Before there were cloud services like AWS, companies had to buy their own servers, install the operating systems, install the necessary tools to run their services, and then build their own. The machine room is not qualified to run those servers.
However, this takes a lot of work, because businesses have to manage their own servers and locations, and spend time dealing with hardware problems, power outages, network outages, etc., and incur a lot of expenses. administrative fees, and personnel costs. Not to mention, investing in a physical server without making full use of its resources also causes waste for businesses.
The Explosion of the Public Cloud
To put it simply, Public Cloud is a form of using Cloud Computing technology to transform physical resources into services provided to users (can be individuals or businesses). Karma).
In the basic Public Cloud model, the provider stores IT resources on-demand through monthly or yearly subscriptions (called subscriptions). They can extend and make them available to users over a private network connection, or over the Internet.
on-premises vs public cloud
Public Cloud is a trend and a way to help businesses replace traditional IT architectures. Enterprises do not need to manage physical servers, do not need to rent server space, and do not waste time and resources operating cooling rooms, and even shorten service installation time. In addition to reducing unnecessary costs, public cloud services also have a commitment to stability (Stabilization), availability (High-Availability) and sustainability (Durability), typically Amazon. Web Services.
Amazon Web Services – “Pioneer” of the cloud computing industry
In addition to being the leader and making strides apart from giants like Microsoft, Google or Oracle, Amazon Web Services (AWS) ALWAYS COMMITTED to very high stability in the services and infrastructure it provides.
Here are four key factors that explain why AWS will give end-users and businesses the utmost confidence in investing in changing or expanding aging IT systems and meeting the needs of their customers. later modern applications.
AWS Infrastructure: Always High Availability
AWS offers the highest level of network availability of all cloud service providers. Each Region is fully isolated and consists of multiple Availability Zones (Availability Zones – AZ, each consisting of at least 2 different data centers), which are completely segregated partitions within the AWS infrastructure.
To isolate all incidents and achieve higher availability, enterprises are encouraged to split applications across multiple AZs in the same region (Region). In addition, the control planes and the AWS Management Console are distributed across multiple regions and include regional API Endpoints. Customers won’t even know if the AWS Management Console or the service API is down!!!
But with AWS, it’s all about design!
That’s right, AWS designs not only routers, the chips in servers and networking devices, storage and compute servers, and speed networks, too. its own high-speed network. All are according to the highest industry standards with great configuration and parameters to meet the huge needs of the world’s users.

AWS Services: The Most Fully Functional
AWS has a lot more services and features inside, than any other cloud provider, including new technologies, like machine learning and artificial intelligence, data warehousing and analytics, or Internet of Things. This helps you move your existing applications to the cloud faster, easier, and more cost-effectively, and deploys faster and with less effort.
AWS also has the deepest functionality of those services. For example, AWS offers the widest variety of databases (including support for MySQL, SQL Server, Oracle Server, PostgreSQL, etc.) purpose-built for different types of applications so you can choose from a variety of tools. suitable for the job for best cost and performance.
In addition, the scalability of AWS services is said to be very easy and can almost be automated, with the right Auto-Scaling configuration (VTI Cloud can assist businesses with setting these policies), EC2 instances can be automatically created to accommodate increased user traffic. Businesses do not have to worry about sales festivals like 11.11, 12.12 or Black Friday… but only need to focus their human resources on promoting business and advertising.
AWS Security: AWS is among the most secure providers
AWS is designed to be the most secure and flexible cloud computing environment available today. The core infrastructure is built to meet the security requirements for militaries, global banks, and other organizations with a high degree of sensitivity.
This is supported by an in-depth set of cloud security tools, with 230 features and security, compliance, and governance services. AWS supports 90 security standards and certifications of compliance, such as CSA, ISO 9001, ISO 27001, ISO 27017, ISO 27018, PCI DSS Level 1, SOC 1, SOC 2, SOC 3… All 117 AWS services store Customer data stores provide the ability to encrypt such data.

Expenses of the business: Use as much as you can, always predict and thoroughly manage costs
We are all too familiar with the payment method of cloud computing services as pay-as-you-go. This feature helps businesses easily calculate the actual cost they will spend to build an IT system, but only pay monthly.
However, there will always be times when the system must expand due to outstanding business growth, or run a test of new technology. Here, VTI Cloud will go more deeply into how customers can easily manage their monthly expenses for proactive interventions, avoiding the cost impact of businesses.
