PUBLIC CLOUD vs PRIVATE CLOUD

The services cloud computing are distinguished primarily in Public Cloud, Private Cloud and a composite form, called Hybrid Cloud. What are the advantages and disadvantages related to each solution? What would be the most appropriate service for your company?

We start to see more in detail what are the available cloud types.

Public cloud
The public cloud is provided by an external provider that, through the Internet, makes available IT resources necessary to support the business of a company. It is a cloud infrastructure is shared by multiple users, in which the provider is also responsible for configuring and managing the service.

Advantages:
Lower costs
One of the main benefits of the public cloud is very competitive costs, due to the elimination of the cost of purchasing and maintaining the IT infrastructure as well as the specialized personnel assigned to service management.

Potentially unlimited scalability
Resources are distributed "on demand", facilitating the change of the level of use.

Greater reliability
Taking advantage of public resources provides increased reliability of service delivery: even if an entire datacenter were to suffer downtime, the network would redistribute the load on the remaining, ensuring continuous access to resources.

Among the disadvantages on the other hand there is less data security, because access is not restricted to one organization. Similarly the data are not in the business but are stored within a shared infrastructure, which can not ensure a very high safety level.

Private cloud
The private cloud has the same basic characteristics of the public, with the difference that it is a solution dedicated to the single organization: the infrastructure is owned by the company, which has exclusive control of data and resources. Usually this type of cloud architecture is handled by our internal specialists, not by eliminating the cost of keeping dellla staff and IT infrastructure.

The big difference between public and private cloud then mainly concerns the placement of the data, which can be allocated to local ownership of the company or within a data center, but above the highest level of security, particularly useful for businesses that handle sensitive data.

Advantages:
Data security and more control over them
As we already mentioned, the main benefit of the private cloud than public resides in increased data security.

Companies that have to do with sensitive data such as financial institutions and banks, they need to protect their environment and through the private cloud can do so safely, having full control of the infrastructure.

Disadvantages:
Higher costs
The private cloud is a more expensive solution, and because it is a dedicated environment, and because it does not delete the costs of maintenance of the infrastructure and technical staff, as is the case in the public cloud. However, many providers offer a fully managed private cloud services that include management cloud in toto, allowing businesses who do not have specialized IT staff available to take advantage of the benefits of this solution.

And Cloud hybrid?
The hybrid cloud can be defined as a mix between the two previous solutions: provides an integrated use of the two structures, combining private and public cloud depending on the business needs. This is a more complex solution to manage, but certainly very versatile and capable of offering tailor the cloud configurations.

Now that we have seen the differences between the different types of cloud, what aspects to choose the most suitable for your business?

Học ngoại ngữ: Tại sao chúng ta cần học từ gốc rễ?

Học ngoại ngữ là một hành trình đầy thách thức nhưng cũng vô cùng thú vị. Tuy nhiên, một câu hỏi lớn mà nhiều người học ngoại ngữ đặt ra là: Tại sao việc học một ngôn ngữ mới lại khó khăn đến vậy, và tại sao nhiều người dù dành nhiều năm học tập vẫn không thể sử dụng ngôn ngữ một cách tự nhiên? Câu trả lời không hoàn toàn đơn giản, nhưng có một nguyên nhân cốt lõi: chúng ta đang học ngoại ngữ một cách ngược chiều. Thay vì bắt đầu từ nền tảng cơ bản nhất của ngôn ngữ nói – âm thanh và cơ chế phát âm – các phương pháp giảng dạy truyền thống thường tập trung vào kiến thức lý thuyết, ngữ pháp và từ vựng, dẫn đến việc bỏ qua những kỹ năng cốt lõi như phát âm, nghe và nói .

Chevrolet Bel Air 1950s

The Chevrolet Bel Air is a full-size car produced by Chevrolet for the 1950–1975 model years. Initially, only the two-door hardtops in the Chevrolet model range were designated with the Bel Air name from 1950 to 1952. With the 1953 model year, the Bel Air name was changed from a designation for a unique body shape to a premium level of trim applied across a number of body styles. The Bel Air continued with various other trim level designations, and it went from a mid-level trim car to a budget fleet sedan when U.S. production ceased in 1975. Production continued in Canada, for its home market only, through the 1981 model year. From 1950 to 1952, the Bel Air Sport Coupe name was used only for the two-door hardtops in the Chevrolet model range, to distinguish the car from the Styleline and Fleetline models. It is named after the wealthy Bel Air neighborhood on the Westside of Los Angeles. 1950 Chevrolet Bel-Air First-year production reached only 76,662 models built. The car cost $1,741 a...

Is Buying Nvidia Stock a Sneaky Crypto Play?

The newest trillion-dollar tech stock offers indirect exposure to the crypto market. Investors are buzzing about Nvidia (NVDA -1.11%) after it reached a $1 trillion market capitalization at the end of May. Now trading at just under $400, Nvidia joins a rarefied elite of just four other U.S.-based companies -- Apple, Alphabet, Microsoft, and Amazon -- with trillion-dollar market valuations. Although Nvidia is obviously a strong play on the future growth of the tech industry, could it also be a sneaky crypto play? That might not be as insane as it sounds. Nvidia already provides the specialized graphics processing units (GPUs) required for cryptocurrency mining rigs. And Nvidia's recent announcement of a new AI supercomputing platform has already led to a flurry of AI-themed cryptos surging higher over the past week. Here's a closer look at why Nvidia might be a way to get exposure to the crypto industry, without taking on excessive risk. The old crypto investment thesis for Nvid...

Xe đạp Road có những loại nào?

Ngoài ra, ở các quốc gia như Mỹ, Châu Âu, còn có trào lưu chơi Cyclocross, kéo theo một dòng xe nữa cũng rất được ưa chuộng đó là xe dòng xe Cyclocross /Gravel Race. Dòng xe Road chuyên leo đèo, nước rút Đây là dòng xe có cấu trúc khung với góc ống đầu và ống ngồi lớn hơn, cùng với chiều dài ống đầu ngắn hơn. Thông thường cấu trúc này sẽ tạo ra tư thế lái vươn về phía trước mang tính tấn công nhiều hơn. Dòng xe này thường cũng có trọng lượng khung nhẹ nhất trong cả 4 loại kể trên, nhưng vẫn đảm bảo được độ cứng cần thiết khi nước rút. Vào thời điểm nước rút và leo đèo, nếu khung xe quá “mềm” (flexible) thì lực đạp từ người lái thay vì chuyển thành động năng khiến xe tiến nhanh hơn thì lại bị khung xe hấp thụ mất. Dòng xe đạp đua Time Trial và Triathlon Xe Triathlon / Time Trial là dòng ...
