Provisioning RDS Instances using Terraform
https://www.zenesys.com/blog/provisioning-rds-instances-using-terraform In this blog post, We will learn to provision RDS instances using Terraform - Infrastructure as Code. Table of Contents: ●    What is Terraform? ●    What is RDS? ●    Installation of Terraform ●    Installation of AWS CLI ●    Configuring AWS CLI ●    Create a Working directory for Terraform ●    Understanding Terraform files ●    Launching RDS instance from Snapshot ●    Launching RDS instances Prerequisites: ●    Installation of Terraform ●    Installation of AWS CLI ●    IAM user Access Key and Secret Key What is Terraform? ●    A tool to create resources, modify and delete them as required. ●    Supporting clouds such as AWS, Azure, GCP, Digital Ocean, IBM cloud etc. What is RDS? RDS stands for Relational Database Services Amazon RDS provides an interface to easily create and manage relational databases in the cloud. It provides salient features such as replication, security, scalability, and high availability with auto-failover. Amazon RDS provides DB engine types such as Amazon Aurora, PostgreSQL, MySQL, MariaDB, Oracle Database, and SQL Server.  With the help of DMS, you can migrate existing DB to RDS easily. Installing Terraform Install terraform using one of the below-mentioned methods. 1.    Using binary package (.zip) 2.    Compiling from source https://learn.hashicorp.com/tutorials/terraform/install-cli From the above link, Download the respective terraform package and install it. Run the below command for checking the installed version. terraform -v Installing AWS CLI A command-line program to create and manage Amazon AWS Solutions resources programmatically Install AWS CLI using below provided command sudo apt-get install AWS CLI Run the below command to check the version of AWS CLI AWS Version Configuring AWS CLI A profile can be configured so that it can be used by the terraforming for authentication. With programmatic access, users will be provided an AWS access key and Secret key. Entire the key and region when asked while executing the below command. AWS configure Understanding Terraform Files variables.tf: A file that holds the access key, secret key, and the region of AWS. What not to do with Access Keys? Not to hard code the keys in a file What should we do? Use AWS CLI profile to pass the secret keys Then we will add AWS keys to the /home/zenesys/.aws/credentials file. Providers.tf: A plugin will be installed using terraform to communicate with the respective providers. Providers such as AWS, Microsoft Azure Services, and GCP, IBM, Oracle Cloud, Digital Ocean. You may also like: Creating EC2 Instances using Terraform Main.tf A template/file which contains a template to provision the resources.  A custom name can be used instead of main.tf Launch an RDS Instance using a Snapshot When there is a requirement to launch an RDS instance from the existing RDS instance, In this case, We will create a snapshot of the existing RDS instance and use it to launch a New RDS Instance with the same data. Let's assume you already have a snapshot in place for an RDS instance, Now we can go ahead and create a DB instance using it. Here is the terraform script for it, We are checking for the latest snapshot of the “dbinstance” DB instance. data "aws_db_snapshot" "db_snapshot" { most_recent = true db_instance_identifier = "dbinstance" } Pass the snapshot_identifier in the template to launch the RDS instance from the snapshot.  Attached is the template below, resource "aws_db_instance" "db_sample" { instance_class = "db.t2.medium" identifier = "sampledb" username = "sample" password = "Sample@#5832" publicly_accessible = false db_subnet_group_name = "${aws_db_subnet_group.db-subnet.name}" snapshot_identifier = "${data.aws_db_snapshot.db_snapshot.id}" vpc_security_group_ids = ["sg-00g52b79"]skip_final_snapshot = true } We can configure the template as required Execute terraform apply the command to launch an RDS instance from the existing snapshot. Launch RDS Instance from Scratch If you’re launching an RDS Instance for the first time,  We need to create the following resources as Subnet groups, Security Groups, Parameter groups,  If, you want to launch it in a desired VPC and Subnet group, If not, Use the below terraform script to launch your first RDS instance using terraform. resource "aws_db_instance" "default" { allocated_storage = 50 identifier = "sampleinstance" storage_type = "gp2" engine = "mysql" engine_version = "5.7" instance_class = "db.m4.medium" name = "sample" username = "dbadmin" password = "DBAdmin@5#41$32" parameter_group_name = "default.mysql5.7" } aws_db_instance – RDS instance as a resource identifier – A unique name for the DB Instance engine_version – DB version to use If you want to launch RDs instances in a custom VPC and subnet groups, You can create the same using Terraform. The VPC where you want to create RDS Instance resource "aws_vpc" "main" { cidr_block = "10.0.0.0/16" } A subnet group (collection of subnets) is a minimum requirement before creating an RDS Instance. Let's create subnets from different availability zones. the private subnet in AZ – A resource "aws_subnet" "priv-subnet1" { vpc_id = "${aws_vpc.main.id}" cidr_block = "10.0.2.0/24" availability_zone = "AZ-a of the Region" } the private subnet in AZ – B resource "aws_subnet" "priv-subnet2" { vpc_id = "${aws_vpc.main.id}" cidr_block = "10.0.3.0/24" availability_zone = "AZ-b of the region" } Now We can create a subnet group using the above subnets A and B: resource "aws_db_subnet_group" "db-subnet" { name = "DB subnet group" subnet_ids = ["${aws_subnet.priv-subnet1.id}", "${aws_subnet.priv-subnet2.id}"]} And We must pass a DB subnet group parameter in the main script to use the subnet group which we have created. db_subnet_group_name = "${aws_db_subnet_group.db-subnet.name}" Once we have the terraform scripts ready, we can execute the following commands to launch the RDS instance. terraform plan terraform apply We can create an RDS instance from Scratch using Terraform in a custom VPC.

Keuntungan & Kerugian Investasi Cryptocurrency
Cryptocurrency adalah coin yang saat ini sedang melambung namanya, jual-beli cryptocurrency mulai banyak bermunculan di dunia maya, seperti bitcoin, ethereum, rippel dan lainnya. Harga yang fluktuatif membuat tingginya minat orang untuk melakukan jual-beli cryptocurrency, berbeda dengan saham yang hanya mendapatkan hitungan persentase saja. Cryptocurrency menganut system peer to peer sehingga siapa saja bisa melakukan jual-beli dengan syarat bisa melakukan kelengkapan KYC. Berbagai situs bisa anda gunakan mulai dari Indodax dan binance, semua exchange tersebut sama saja mengikuti harga asli cryptocurrency di seluruh indonesia. Anda bisa memilih berbagai macam cryptocurrency tersebut sesuai keinginan, karena tidak ada batasan untuk membelinya asalkan anda mengerti keggunaan coin tersebut untuk apa. Oleh karena itu, banyak orang yang belum paham keuntungan dan kerugian ketika melakukan jual-beli cryptocurrency, agar anda bisa paham perhatikan ulasan berikut! Keuntungan Investasi Cryptocurrency 1. Potensi Kenaikan Harga di Masa Mendatang Sudah sering Anda dengar bukan, bitcoin dan mata uang digital lainnya sudah membuat puluhan orang kaya raya mendadak. Trend yang meningkat dengan luar biasa adalah bukti otentik di masa lampau. Bagaimana di masa depan? Bahkan penyihir pun tidak akan bisa meramal dengan tepat, tapi belajar dari pola yang ada, maka potensi kenaikan nilai bitcoin di masa mendatang bukan kemustahilan. 2. Kebebasan dan Kecepatan Bitcoin, ether, dan mayoritas mata uang kripto lain menggunakan teknologi blockchain tanpa melibatkan pihak ketiga yakni perbankan. Dengan demikian, tidak ada aturan-aturan yang berpotensi menghambat proses payment. Misalnya ketika melakukan transfer ke luar negeri, maka prosesnya tidak perlu menunggu hari kerja, tapi cukup dengan hitungan jam bahkan menit. Kenapa bisa semudah dan secepat itu? Karena pada prinsipnya, tujuan awal penciptaan mata uang kripto adalah untuk menghilangkan hambatan-hambatan di dunia keuangan. Meskipun saat ini, berbagai startup mulai melirik menerbitkan mata uang kripto sebagai sarana crowd funding melalui ICO. 3. Keamanan Identitas Di dunia ini, ada saja orang yang memiliki kebutuhan aneh, macam menyembunyikan identitas ketika bertransaksi. Eits, jangan negative thinking dulu dah ah! Bisa jadi karena ogah info personalnya diketahui Bank atau oleh merchant. Info semacam itu berharga dan rawan disalahgunakan lhoh. Maka dari itu, beberapa orang memilih menggunakan BTC dan ETH untuk menjamin informasi yang ada. Tapi jangan digunakan di Indonesia, dilarang ntuh buat jual beli. 4. Menghindari pemalsuan uang Salah satu problem dari penggunaan duit kertas maupun kartu kredit adalah rawan pencurian dan pemalsuan. Secara teknis di dunia digital, ada istilah “double spend”, yang bermakna dengan menggunakan uang yang sama, seseorang melakukan transaksi untuk dua hal yang beda. Skema blockchain di mata uang kripto tidak memungkinkan hal ini terjadi, bisa dibilang aman! 5. Berpartisipasi dalam ICO Sudah tau apa artinya ICO? Pernah loh saya tulis tentang Initial Coin Offering. Dimana perusahaan yang punya proyek, nerbitin mata uang digital untuk membiayainya. Nah hebatnya, banyak ICO membuat orang menjadi kaya karena proyeknya berjalan dengan lancar sehingga nilai koinnya meningkat luar biasa drastis. Kita pake contoh lagi deh. Misal proyek X menerbitkan Xcoin dengan harga ICO USD 0,01 per token(coin). Kemudian dalam setahun harganya meningkat menjadi USD 1 per koin. Naik 100 kali lipat dong! Terus apa hubungannya dengan mata uang digital lainnya? Saat ini, sebagian ICO minta BTC atau ETH untuk Anda yang mau berpartisipasi dalam proyek mereka, bukan melalui transfer duit konvensional. Itulah kenapa, paling tidak harus memiliki mata uang kripto kalo mau berpartisipasi dalam ICO. Kerugian Investasi Cryptocurrency 1. Volatilitas Sangat Tinggi Heiy, di intro kan sudah saya jelaskan masalah volatilitas ini! Jadi sabar saja ya, mudah-mudahan lekas ketemu nilai wajarnya. Jadi investor dan company yang mau ICO bisa tenang gembira. Nah, tapi Anda juga tidak boleh abai terhadap beberapa poin lain yang berpotensi mengganggu investasi kita. 2. Potensi pelanggaran Hukum Masalah utama dan paling pelik yang dihadapi oleh mata uang digital adalah regulasi. Seandainya semua negara di dunia melarang bitcoin, bisa dipastikan nilainya akan runtuh dan tak berharga. Kenyataannya tidak bukan? Ini karena beberapa negara sudah mengatur dan mengijinkan penggunaan mata uang kripto. Bahkan Swedia dikabarkan sebagai negara pertama yang ikut menerbitkan mata uang kripto-nya sendiri. Saya sendiri melihat beberapa perusahaan keuangan global enggan menerima bitcoin dan semacamnya karena takut mengganggu bisnis yang selama ini telah dibangun. Eksekutif dari JP Morgan sampai melarang karyawannya beli bitcoin lhoh, dan itu menggelikan menurut saya. Jika permasalahan dengan regulator sudah usai, nampaknya peningkatan valuasi mata uang kripto tidak akan bisa dihindari. 3. Kehilangan “kunci” wallet Pastikan Anda mencatat di komputer atau kalau perlu di print dan disimpan di beberapa tempat. Karena apabila Anda lupa dan kehilangan kunci wallet Anda, maka akan sangat susah dan hampir mustahil bisa mengakses dompet Anda. Salah satu solusi yang menurut saya bisa dijadikan pertimbangan adalah menggunakan apps di handphone, tentu harus lebih user friendly dan mudah digunakan. Kali ini saya bekerja sama dengan Luno dan sudah mencoba keunggulannya sebagai wallet Bitcoin dan Ether. Nah jadi sembari nunggu perkembangan dunia per-kripto-an, Anda bisa mulai mendaftar ke Luno. Apakah harus Luno? Silakan Anda coba aplikasi yang lain dan pilih sesuai keinginan masing-masing. Tapi menurut saya, wallet Luno adalah salah satu yang paling aman! Tapi sebelum memutuskan mencari aplikasi lainnya, pastikan bahwa penggunaannya harus mudah dan secure. Apa gunanya Anda mendownload wallet jika ternyata tidak meminimalisir kemungkinan kehilangan token cryptocurrency.

TOP SOFTWARE DEVELOPMENT TRENDS OF 2021
Many elements in our lives have changed to overcome the obstacles we encountered in the last years. And certainly one of them was the digital landscape. The necessity to prepare to return to the normally needed complex judgments from the point of view of technology. The previous approaches needed to be relaxed and the options increased in order to anticipate a more linked globe with the endless capability to safely conduct organization remotely. Digital businesses' exposed flaws showed that characteristics, such as adaptability and resistance had to be acquired. Modern corporate architecture must be flexible to respond to change. Resilience means that the workflow of an enterprise must be able to resist disturbances. Within the realities of a hybrid office, this new paradigm has been developed with the necessity for greater security and the automatic features of renewables and all checks. In fact, a leading software development company is quite close to the new paradigm of the globe. Rebooting services in the crucial areas will both satisfy creating and relaunching a product by implementing fresh techniques. And here are some trends in software development that enable companies to align themselves in a short time. Advances in the monitoring, analysis, and readily adaption of all users and customers of all parts of the world have been implemented for many years now by software development technology. In the last decade, Java and Python have been used by more individuals throughout the world. Both languages will take the lead in the top 10 trend technologies to be mastered in 2020. Let us look closely at the software developers and the rising technologies to welcome us into a new groovy 2.0 digital enterprise. Cloud You might argue that flexibility and resilience are not a new paradigm. Someone probably campaigned for this previously in the 1960s. However, the requirements of distant workers in various businesses have exposed new phenomena, known as Hybrid Office for several decades. The Internet has been present. The Hybrid Office Infrastructure has become a pillar of the new paradigm within a few months. More organizations have made modifications to support this tendency, which is becoming the new standard. Fortunately, there have already been some new trends in software technology to address most of the demands of a hybrid office infrastructure service. DevOps and Business Intelligence The IT sector has also evolved with transformational commercial solutions. As the new technology adapts procedures in Expert DevOps software development, IT integrates a cross-functional workforce, creating a wonderful atmosphere for balanced innovation. DevOps and BI are therefore here to serve the best and this year are the hottest developments in the software business. Big Data Big data is an important part of the industry; it was particularly important in the fields of health and automotive. Instead of saving data on the spot after each computation, the current advances in software technology are allowing data processing. The processing in the batch is also on the watch. Cybersecurity Cybersecurity is a pioneer where the primary aim and driving factor for organizations are constant growth and change, establishing confidence amongst their customers. Cybersecurity framework may also be facilitated by controlled user access, firewalls, data, and app security, data analysis, and machine learning algorithms. Compliance Legislative changes are being introduced with new technologies in software development. Governments must change processes and treaties immediately to address both advances and hazards of immediate access to data. Companies that add more categories of products or expand to new markets should continue to comply with local taxes. In addition, the compliance activities and the coding of available niches for IT personnel have been expanded. Emerging Technologies Emerging technologies are committed to innovation and are among the latest software trends. They allow creating and building goods in a short period of time as part of complicated solutions. AI/Ml A more outstanding new AI/Ml technology can be hard to identify amid trends in the software business, such as artificial intelligence and machine training. Their fields of use are rapidly unfolding. The triumph of AI in the financial and film sectors was achieved in 2021. It is utilized for forecasts of investment. It demonstrates excellent performance evaluating movie screenplays and calculates high accuracy in box office revenue. Human Enhancement Human increases are utilized to strengthen the body's biological performance. Sensory implants, prostheses, and exoskeletons improve physical sensations through nerve stimulation. Human growth is also one of the technologies to be used in the near future to include artificial intelligence. In order to maintain pace with the enemies, AI agents will be given information to the military Space Force commanders. IoT The Internet of Things is a network of physical items with integrated technology to connect, identify or interact with external surroundings. The Internet of Things. IoT is now looking to the industrial sector. It has started something modest as smart home and consumer-focused devices. A digital revolution of the production and supply chain areas is allowed through new IoT-based installations. AR/VR Augmented reality (AR) was originally a fun virtual real-time add-on in text or media layer that adds value to the interaction between the user and the actual environment. This technique differs from simulation, which requires the display of a digital screen. Starting to pave the road for AR to become a navigational tool in the automobile sector. The driver presents the current speed and route directions on the windshield of a car. 5G A newcomer to the new technologies family is 5G and How Can 5G Transform the IT and Software Development Industry?. It is the cellular standard of the following generation after 4G. The new system architecture includes core network cut and edge calculation and aims at a maximum of 20 Gbps and 10 Gbps of downlink and uplink throughputs. 5G is strongly dependent on sectors like intelligent cities and defense installations that need greater security attention. Quantum Computing Quantum calculation works on subatomic particles in the quantum state. Qubits can process tremendous computational complexity in their superposition. The technology is, however, not yet available to the public. Quantum computing will be used in the financial and security industries in the near future for portfolio analysis. Many ideas are being implemented into cryptocurrencies and Blockchain after quantity encryption as well. Blockchain Blockchain is still taking the globe. Blockchain covers sectors beyond finance (Defi) and government via the three pillars known as decentralization, transparency, and immutability. In sectors such as supply chain management, Blockchain has fresh beginnings. Custom Blockchain development technology will give a reliable picture of the glass panel to move the goods from producer to dealer. Summery Many believe that after being encouraged to shift, one is no longer comfortable with the usual rigidity that defines how it all works. The trends in the software business modestly shaped the new goals of softly upgrading finance, SMBs, SMEs, and the enterprise level, governmental, medical, automotive, and energy sectors, among others in 2021, with a constant public desire for new technologies, whether for work or personal uses.
