Understanding the concept of IaaS

 After all, what is the cloud service essentially about? Understanding the IaaS (Infrastructure as a Service) model, or Infrastructure as a Service, is a good place to start. Basically, it involves hiring an IT infrastructure - data center, hardware and software - as a service, avoiding the complexity of purchasing and managing local servers.


The company starts to remotely manage virtual machines, storage space, installed software, etc. Basically, the physical infrastructure is replaced by a digital model and the equipment itself is located in the physical space of the service provider.

JNCIA Engineers must support network Infrastructure through the use of TCP/IP protocol. Their responsibilities include IP addressing, subnetting and Network Address Translations. 

Having defined this concept, we can identify the points to be considered before migrating to the cloud.


Why is the IaaS gaining more and more strength in Brazil?

The moments before the migration

We can divide this process into two stages: planning and execution. In planning, it is essential to identify each of the actions to be performed during the execution. Therefore, we will highlight here crucial issues for efficiency during and after the transition.


1. Defining the company's needs

It may not seem like it, but a very common mistake is migrating to the cloud without an accurate assessment of the company's needs. It is essential, first of all, to identify the user profile of your business: which space is used for data storage, which applications are run on a daily basis, which data transfer rate and the availability of links etc.


The assessment of the level of security required, according to the confidentiality of the company's data, must be raised, so that it is possible to confirm that the provider meets expectations. In short, you need to put on paper all the prerequisites that the service must offer to meet your IT demands.

2. Definition of infrastructure

After surveying what the company's needs are, it's time to decide on the infrastructure to be hired. What type of cloud should be adopted: public, private or hybrid? What is the total storage capacity (CPU), memory (RAM) and disks to run all applications? Will they be allocated on individual or independent servers?


In addition, it is necessary to deal with the issue of software licensing. To implement Microsoft applications, for example, you need to establish a software assurance contract. In turn, databases SQL and Oracle require verification that their licenses allow the migration to cloud.

International English Language Testing System (IELTS)

 It has existed for almost 30 years and is one of the most widespread tests around the world. It aims to test a candidate's level of communication in English using four language skills with a real context: oral interpretation (30 minutes), text interpretation (60 minutes), writing (60 minutes) and conversation (15 minutes). Developed by the British Council in partnership with the University of Cambridge, it is applied in 16 cities in Brazil.

However, there are reports that renowned institutions require a score higher than 8. It is also important to say that IELTS is applied in two formats: academic and general training. The academic is aimed at those people who are looking for opportunities to study master's, doctorate and postdoctoral studies abroad. General training, on the other hand, is focused on those who seek professional impr

Prevention and Recovery: How can security tools help?

 Heavy rains, floods, landslides, devastating fires, blackouts that left an entire state without electricity. Unfortunately, the list of disasters that occurred in Brazil during the year 2020 is long. Disasters appear unexpectedly, generating terrible results and, often, irreversible damage. Within a company's scenario, it is not much different. Just as nature is subject to disasters and risks, so are companies. Therefore, information security works to protect data and information within the business environment, through tools and actions that act in the prevention and recovery of data in disaster situations. In this article, you will understand how security tools can help in a disaster scenario, and why it is important to have complete and continuous actions to protect your company's data. There are two reasons why people underestimate threats and risks: ignorance and minimizing results. Although we are in the information age, the significant increase in the cost of data leaks

How to increase visibility and mitigate risks in the corporate network?

 Corporate networks are changing rapidly as companies embark on Digital Transformation, expanding on the Cloud, incorporating IoT devices and increasing wireless access. All of this increases the attack surface, making the environments more complex.  Protecting this new environment and blocking more sophisticated and intelligent cyber threats has been a major challenge for IT. Therefore, it is necessary to invest in tools capable of giving quick and accurate responses to any type of attack. The problem is that, as the context and visibility are compromised by the complexity of the environment, the IT team ends up having trouble screening many alerts at the same time.  As a result, response times are delayed and teams are often unable to accurately screen all alerts, allowing potential threats to go unnoticed. To deal with this new reality, companies need robust and efficient protection solutions, such as Gigamon's ThreatINSIGHT. It is the cloud's first native high-speed network
