Do So

Abstract—Cloud computing has been the trending model for storing, accessing and modifying the data over the Internet in the recent years. Rising use of the cloud has generated a new concept related to the cloud which is cloud forensics. Cloud forensics can be defined as investigating for evidence over the cloud, so it can be viewed as a combination of both cloud computing and digital forensics. Many issues of applying forensics in the cloud have been addressed. Isolating the location of the incident has become an essential part of forensic process. This is done to ensure that evidence will not be modified or changed. Isolating an instant in the cloud computing has become even more challenging, due to the nature of the cloud environment. In the cloud, the same storage or virtual machine have been used by many users. Hence, the evidence is most likely will be overwritten and lost. The proposed solution in this paper is to isolate a cloud instance. This can be achieved by marking the instant that reside in the servers as "Under Investigation". To do so, cloud file system must be studied. One of the well-known file systems used in the cloud is Apache Hadoop Distributed File System (HDFS). Thus, in this paper the methodology used for isolating a cloud instance would be based on the HDFS architecture. Keywords: cloud computing; digital forensics; cloud forensics

Network File System

Layanan dan data teknologi Cloud Computing tersimpan pada server, hal ini menjadikan faktor pentingnya server sebagai pendukung ketersediaan layanan. Semakin banyak pengguna yang mengakses layanan tersebut akan mengakibatkan beban kinerja mesin server menjadi lebih berat dan kurang optimal, karena layanan harus bekerja menyediakan data terus-menerus yang dapat diakses kapanpun oleh penggunanya melalui jaringan terkoneksi. Perangkat keras server memiliki masa performa kinerja. Hal serupa dengan perangkat lunak yang dapat mengalami crash. Dengan fungsi server yang memberikan layanan kepada client, server dituntut untuk memiliki tingkat availability yang tinggi. Hal tersebut memungkinkan mesin server mengalami down. Server juga harus dimatikan untuk keperluan pemeliharaan. Penelitian bertujuan ini membangun Clustering Server yang dapat bekerja bersama yang seolah merupakan sistem tunggal diatas lingkungan virtual. Hal ini merupakan solusi untuk mengatasi permasalahan tersebut. Pada penelitian ini penulis menggunakan server virtualisasi proxmox, FreeNAS sebagai server NAS dan DRBD untuk pendukung ketersediaan layanan tinggi dalam lingkup HA, sinkronisasi data dalam High Availability (HA) yang dapat melakukan mirroring sistem kemesin lain. Dengan diterapkannya metode HA dan sinkronasi DRBD serta penggunaan NFS (Network File System) pada sistem cluster didapatkan hasil rata-rata waktu migrasi sebesar 9.7(s) pada node1 menuju node2, 3.7(s) node2 menuju node3, dan 3(s) pada node3 menuju node1. Didaptkan juga waktu downtime yang lebih sedikit yaitu sebesar 0.58 ms pada node1, 0.02 ms pada node2, dan 0.02 ms pada node3.
