The challenge of hybrid multicloud
Even with edge computing and distributed clouds maturing, an important obstacle remains. In general, companies would like to have multiple clouds to allow for increased innovation, avoid supplier blockages and allow the use of the best cloud for each work profile.
Creating a multicloud environment requires companies to deploy virtual infrastructure in each cloud, and each infrastructure needs to be managed separately. And, as today's public clouds are designed, applications deployed across multiple distributed cloud infrastructures cannot be easily connected.
This challenge has led many IT decision makers to find that their infrastructures are, in fact, becoming more complex. According to a recent survey by the Enterprise Strategy Group , digitally mature organizations were three times more likely than those without digital transformation initiatives to say that IT is significantly more complex today.
The cloud distributed at the edge will help pave the way for the true multicloud of the future, allowing companies to seamlessly manage on-premise services and services spread across different clouds as if it were a logical cloud with minimal infrastructure duplication.
Vendor-neutral interconnect solutions are also helping to solve the challenge of hybrid multicloud, providing cloud ecosystems, operators and companies with high speed, low latency and virtualized connections worldwide.
In this way, CSPs can distribute and scale computing storage where they need to be, while allowing companies to access multiple interconnected CSP services.
The professionals will examine and evaluate security strategies and defenses. It is the responsibility of the Cyber Security Specialist to create new defensive systems and protocols.

Establishing your work / personal profiles
First, we need to create the base that will feed the entire configuration and allow you to keep the two profiles separate on your phone. And for that, we will use a feature of the Android phone that is often overlooked: the ability to log in as multiple users on the same device.
It's something that has really been available on Android phones since the Android 5.0 era of 2014 (and even before that, when it comes to tablets), but which has been increasingly buried and underutilized over the years.
It is also part of the same broad system that allows Android guest mode, which improves privacy, that I wrote about in the beginning of the fall.
However, there is an annoying asterisk: just like in guest mode, Samsung , for no apparent reason, has chosen to remove this standard element of the operating system entirely from the software on its phones. So if you're using a Samsung device, unfortunately, you're out of luck.
For the rest of us, what we’ll do is add a secondary user to our phones and then frame the primary user as a work profile and the alternate user as a personal environment. If that seems like a lot to do, don't worry: we're about to share everything step by step.
To get started, pick up your phone and do the following:
Open the system settings and go to the System section.
Touch "Advanced" followed by "Multiple users".
Turn the toggle button on the screen that appears in the on position, tap the line labeled "Add user" and enter the name you want for the secondary user. Try to give the name something distinctive and obvious - like "Personal profile", "Personal Susie" or whatever makes sense to you (especially if your name is not Susie).
Activate the toggle button next to "Activate calls and SMS" so that the phone works fully for this new secondary user.
(If you are using a device where the manufacturer has arbitrarily changed the normal Android layout and you do not see the exact range of options described above, try searching your phone's settings for multiple users . As long as you are using an Android device 5.0 or later and your phone was not made by Samsung, this should take you to the appropriate and equivalent location.)
Understood? Good. Now it's time to optimize this new environment so that it focuses on your personal interests and puts all business related items as out of sight, out of mind as you would like them to be.
working as a Cyber Security Consultant means that you will be responsible for keeping a client’s data suitably protected and free from the risk of cyber attacks and related problems.

Behind the Code Marathon
The young Igor Ventorim , 25, has good reasons to close 2020 in a celebratory atmosphere. He came in 4th place in the general ranking of Brazil for the Behind the Code Marathon and, coincidentally, conquered the same position in the final challenge in Latin America. An excellent performance, which surprised him.
Igor did not consider the possibility of being among the Top 100 in Latin America. "At the beginning of the competition, my goal was only to enter a top 10 of any of the challenges, and I didn't even intend to go until the end of the competition," he says. But when the rankings started to be released, he was determined to go as far as he could. "Getting to the final was possible," he realized.
Igor's life is intertwined with the Federal University of EspÃrito Santo (UFES). Born in Serra, near Vitória, he has a degree in Computer Science and a master's student in Informatics. He also works as a civil servant in systems development, at the university itself.
Your guide to a future without Ransomware!
The fact of studying and working required Igor a great personal and mental effort to perform well in the competition. Right from the start, one of the biggest obstacles was to reconcile the time to dedicate to the Marathon with his daily chores.
More than the organization, however, one of its greatest challenges was having to relearn how to manipulate technologies that it had not used in a long time, and still know new ones. "I am not a genius, anyone can be among the finalists in this competition. It is a matter of dedication and effort. This dedication is always important, much more than chance or luck â€.
Still with his student spirit, Igor says he learned a lot from the Behind the Code Marathon. The main lesson was to keep your feet on the ground and your head in the real world. "You need to analyze and understand the problems calmly, showing how it should be done in real life," he describes.
The Computer Systems Analysts must identify the progress made towards implementing monitoring by application and by the environment.

How to disconnect from projects that no longer make sense to you
Most likely you have already lived this experience: you started to participate voluntarily in a project and, with the passage of time, the mood about it decreases. But then the problem arises: how to get rid of this commitment?
Read more: Managed LAN Service
Coach in time management and founder of the company Real Life E Time Coaching & Speaking, Elizabeth Saunders went through this recently: the interest ended after years in a discussion group and, despite still having the event on her agenda and participating in exchanges group messages, did not know how to inform their departure.
In an article for the Harvard Business Review, the professional tells how she solved this problem and the relief that this resolution brought. "I was surprised to see that, once that commitment was broken, I immediately felt lighter and freer as clouds of indecision and escape disappeared. So, it was not my fault, â€he said.
Below, we present the four steps taken by Saunders to "say goodbye†to an activity that is no longer appreciated. Check out:
1. Be direct
In the text, Saunders presents the email sent by her announcing her departure from the group as an example of content that can be used in these cases. The message was this:
The future of Interconnection
Webinars by:
Hi (name of leader),
All right? I would like to communicate a few things.
When assessing my priorities, I realized that (group name) is not an area where I find myself investing my time.
I thought I could be more present last year than I was, and I don't see myself participating in the coming months. I would like to make this announcement directly so that you do not count on my presence to achieve the group's goals.
Thank you for the opportunity to join the club. It was a great learning experience for me. I am very proud of everyone for the progress we have made. I will be back in the future when and if the group is aligned with where I feel I should be.
The Computer Systems Analyst uses object-oriented programming along with client and server applications development processes, multimedia and Internet technology.

Advantages of each type of cloud
Now that we have identified and conceptualized the types of cloud, let's see what are the advantages and the main applications of them.
Read more: Managed Meraki Services
1. Private cloud
The private cloud is useful for industries that have few branches and do not want to depend so much on data communications over the internet, when performed in the company's own physical installation (the vast majority of cases). It is also used when the contractor wants to maintain his investment in assets (equipment) but seeks a more physically secure environment than his own facilities, allocating his equipment within private spaces in professional data centers. In general, this type of cloud is indicated for companies willing to invest in IT equipment and centralize the infrastructure in the headquarters or in professional data centers.
The private cloud obliges the client to hire a team (internal or outsourced) of specialists in IT infrastructure, with varied skills (virtualization, database, operating systems, maintenance and configuration of equipment and networks) and does not allow cost sharing of this team and equipment among several customers. It is usually limited to very large companies that have a centralized strategy for their IT. It can also be recommended in case of a great shortage of quality internet. It is important to note that private clouds have very high costs.
2. Public cloud
Unlike the private, the public cloud is for companies that want to avoid a centralized IT architecture. Today, in many cases, the architecture is still hybrid, in a progressive process of migrating applications from the on-premises environment to the public cloud.
The public cloud offers a very high level of security (physical and logical) and availability for the IT environment without having to invest in equipment and licenses, transferring IT expenses from CAPEX (Capital Expenditure, or capital expenses, are the costs acquisition of equipment and facilities) for OPEX (Operational Expenditure, or operating expenses, as it is an infrastructure contracted as a service, which allows constant adjustments), providing operational and financial flexibility.
The public cloud is always more economical than the others and it can offer a level of security much higher than local environments, as it has a wide structure to guarantee physical security, and several layers of logical security through software, appliances, backups and settings. Public cloud providers must operate in data centers with an international Tier-type certification to extend physical security. This type of cloud prevents companies from having to immobilize their capital in assets that are not part of their core activity, or even finance investments in new equipment, in a period when financing is expensive and scarce.
The Computer Network Support Specialists are the trained experts and are extremely helpful in the computer networking of an organization. They provide assistance and guidance to system users and businesses.
3. Hybrid cloud
The hybrid architecture allows to host each system in an environment according to the availability and security required, as well as the investment budgets and monthly costs defined by the company.
A point that draws attention when choosing a hybrid cloud is the difficulty and time to manage different environments. This complexity is also not restricted only to the operation, but to the financial requirements of allocating costs and investments, which become more complex to be measured and managed.

Why is the cloud an indispensable technology for startups?
Startups are innovative companies in terms of providing services and selling digital products. When we say innovative, we mean that they use cloud resources far beyond data storage, like most conventional companies. Startups work in the cloud. That is, they need resources and tools that allow them to structure their vital operations in the cloud.
Know more: Managed LAN Service
These companies want to consume the resources they need to grow, but in the right measure (size and exact moment). A newly opened startup, for example, may not have the necessary funds to buy equipment and rent a place to work. The solution would be to rent the infrastructure the size it is today with the advantage of being scalable in the future.
This is perhaps the biggest benefit of the cloud for startups, because, usually, to open a company and start operations, the entrepreneur needs money to invest in physical infrastructure and working capital. With the cloud, this need falls considerably, allowing the initial capital to be invested in what generates revenue.
Professionals certified as Microsoft Office Specialists, efficiently perform their work in a timely fashion alongside non-certified professionals
For example, instead of forming a physical structure of its own, the startup can outsource, renting what it needs to run its operations. Thus, more resources are left to invest in the core business of the business, in its core business, increasing the chances of growth.

Cybersecurity issues in Brazil
As we said, Brazil is today the country in Latin America that suffers the most cyber attacks. This poses a huge risk to the government, businesses and the entire population. After all, already in a first analysis, if the market data is at risk, the country is no longer an interesting attraction for investments.
Even so, the Brazilian people and companies are still not properly aware of the size of this risk. The idea that this "only happens to others" is a myth that needs to be left behind. The damage can already be seen here and it is necessary to understand the real size of this threat.
Know more: Managed LAN Service
All of our devices are constantly connected to the network - from smartphones and computers to the new generation of electronics, such as televisions, refrigerators, etc. In addition, it can be seen that most Brazilians do not have the minimum security in their devices. We are talking about firewall, antivirus, VPN, among others.
All over the world, even automated programs are already in place to automatically search for security holes in any devices. They are called bots: software that acts as a hacking robot, scanning the internet and pointing out targets for attacks.
The Microsoft Certification professional remains vital for companies and network centers to perform their day-to-day responsibilities.

Understand why investing in cybersecurity in your company
Investing in cybersecurity has never been a greater necessity. The digital transformation and the constant increase in the value of data for the success of a business have made corporate systems constant targets of attacks and both processes and the protection of IT infrastructure and applications have become mandatory.
In this post, we will discuss a little more about this importance and what to do to ensure success in information security strategies, listing reasons to invest in this area. Come on?
MCITP Database Administrator job role involves designing and developing logical data models, create physical databases and create data services by using Transact-SQL.
Avoid data compromise
The priority issue in cybersecurity is to protect information of a confidential nature, such as customer data, and operational - data on productivity that keep corporate secrets or that are fundamental to the routine operation of the company.
Therefore, the most important return on this investment is in the health of the business. As a professional in the field, you understand this and need to use your influence to convey this message to other boards.
Among the biggest mistakes made today by companies is treating cybersecurity as a secondary expense and not understanding its relevance at the core of the business: protecting transactions, shielding the system and the need to increase productivity without exposing yourself. This goes for any size of company and for any area of ​​activity.

What are the advantages of the hybrid cloud?
The flexibility of the hybrid cloud brings several benefits to the business that invests in this technology. Know the main ones:
Performance optimization
In the hybrid cloud, the manager can always modify the location where the resources are hosted. This ensures a higher level of performance for the enterprise: whenever necessary, the application can be directed to the public cloud and scaled according to demand.
Greater responsiveness to customer demands
Because the hybrid cloud is scalable, it gives the business the ability to respond quickly to customer demands. The teams will be expanded with the support of outsourcing companies and everyone will have the necessary resources to carry out their activities normally.
Better availability
In the hybrid cloud the company has maximum availability. If any problem occurs in the private cloud, just direct access to the public cloud (and vice versa). Thus, delays are less recurrent and the company gains competitiveness.
We can mention as an example the use of virtual machine tools. Flexible, these solutions can be easily placed in a new environment when the company needs it, avoiding delays in delivering results.
The Linux administrator has an active role in patching, compiling, securing, and troubleshooting Linux servers in a heterogeneous environment. The professional performs system updates and server configurations.
High mobility
Remote work routines are already incorporated by several companies. With the hybrid cloud the company can direct any tool to the cloud, ensuring that this type of process is maintained smoothly. In other words, even if your enterprise has a personalized integrated management system, it can be accessed via the cloud without compromising the user's security.

Why do criminals use these coins?
The great motivation for the use of virtual currencies in cybercrime is privacy. The encryption involved in transactions omits data from payers and receivers, something that inhibits and makes it very difficult for the authorities to track illegal activities involving cryptocurrencies.
It can be said that, in the face of other types of monetary transactions, those involving virtual currencies are practically invisible, after all, cryptography does not allow the tracing of the money path.
The cryptocurrency transaction system is an easy and anonymous conduit for handling large amounts (it is worth remembering that a Bitcoin is quoted at more than 30 thousand reais) without the need for bank verification.
In addition to this detail, there is an entire virtual ecosystem that adopts virtual currencies for illicit purposes and, in a way, cooperate so that gangs are able to "clean up" dirty money and then exchange virtual currency for conventional money. Factors like this help to tarnish the image of cryptocurrencies. All this ease of manipulation and conversion does not pass
unnoticed by cyber criminals, who start using cryptocurrencies in their modus operandi, so much so that many gangs that apply scams using Ransomwares or Phishing tactics ask for the rescue of the information obtained in the form of virtual currencies, something much safer for them than any redemption request with physical currencies.
Faced with this new reality of financial transactions in an anonymous and protected way, a range of options opens up for cybercrime, which takes advantage of a legal activity to mask illicit gains and hinder investigations by the authorities.
More about the juniper jobs.
It is important to emphasize that, in order to avoid any type of disturbance, avoiding virtual gangs, it is essential to establish consistent security processes and policies, which are supported by good protection tools to make attacks more difficult.
